As a doctoral researcher, I have to acknowledge your well-designed methodology for the analysis. Two thumbs up!
Thanks man, trying to collect and share useful data!
Thank you for your time and effort doing the tests. It was very informative 👍🏻
Thanks, glad you got something out of it!
Thorough and forensic!
the big key to solve is what target material works best to extend bolts life!! ive been trying many different materials. im finding that hard wood metal or poly backbored as last layer positive bolt stop., then foam, rubber, or styraphoam or clothing layer no thicker than the bolts flight beginning. keeping flights from ever contacting target material extends the life of the bolt majorly!! so my targets material layer is always 3" or less before the positive stop last layer! new bolts get flights detached then stick open bolt in foam super glue 2/3 drops into bore to strengthen tip bolt hold, let cure 24 plus hrs. then super glue flight and tap back into bolts and let cure another 24hr or so! a little extra work in the beginning and i still have most of all bolts i buy shooting daily. random acts of violence on glass bottles or metals laying around is worth destroying a couple every now and then.
great video waiting for my bow from steambow so excited
Thanks, you're definitely going to love your bow!
Nice very informative
Very good video.
Thank you for your video
nice information.
Good stuff man
Cheers
Just landed on your channel ,subbed 👍great content thank you 🙏
Thank you. Also nice music choice
Funny how the cam cant pick up the bolts sometimes. Thats speed
Thanks!
Imo they could of put an actual trigger box/string latch like a pse viper for the kinda money they charge. Its just a cobra with a magazine and a horizone redback limb
I also experience that sometimes those Steambow bolts bend or tips go off. I am currently shooting with 35lbs limb only. I glue those tips with superglue back together and straighten bent bolts with hand and continue practice. When gluing tips for broadheads, make sure your broadhead tip is aligned with vanes.
Good information for everyone, thanks!
thank you, sir.
You give good info without the macho BS - thanks
Thank you, that's good motivation to keep up this project!
Great Video. One question, can I use the adder bolts in the Stinger Tactical magazine?
Or are there any cheaper alternatives to the original Steambow bolts?
Adder bolts are around an inch too long, and probably too thick to pass out the front. Any bolt about 6.3 inches long should work, and there are various options that pop up on Amazon and ebay. I have had good success with 6.3" carbon bolts from China, delivery takes a few weeks but they hold up great even with 90 pound limbs. These, for example (www.ebay.com/itm/265705991624?_trkparms=amclksrc%3DITM%26aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3D18a53c5dc3cf447b838773c5ba054d47%26pid%3D100675%26rk%3D1%26rkt%3D15%26sd%3D265705991624%26itm%3D265705991624%26pmt%3D1%26noa%3D1%26pg%3D2380057&_trksid=p2380057.c100675.m4236&_trkparms=pageci%3Ab3ce1b03-3420-11ed-bf6c-da13a76e15f0%7Cparentrq%3A3bc434681830a45e574e7622ffff6ba4%7Ciid%3A1)
I'd really like to see you doing a review of their new siege crossbow
I got my stinger 2 tactical in 2022 and got an additional 90lb limb. It's been a while and I went back to check them out and notice they now have higher weighted limbs and heavier weighted bolts. I don't plan on a heavier limb as I think the 90lb is perfect for home defense, however I noticed they now have a disclaimer that for 90lb limbs should not be used with regular bolts as it will damage equipment ? In your opinion is this valid or just some bs to get you to buy the newer heaavier weighted stock ?
I believe it to be valid. This is a fundamental aspect of archery in general, that shooting arrows or bolts that are too light for the draw weight leaves too much energy in the bow and system, which accelerates wear or can at worst cause some breakage. Another angle is that based on good, thorough velocity measurements and energy calculations from compound bows that I have seen, shooting heavier arrows from a given draw weight will generally translate a small percentage more of the available energy in the bow into kinetic energy.
I think 90 lb is definitely adequate for home defense, based on my meat target tests. A good balance between speed of cocking/follow-up shots and penetration. But I shoot 150 grains as a minimum from 90 lb.
Good video. Tried the new Adder throwing arm? The etreme? BTW, it's bolts or quarrels for crossbows, not arrows :)
Hi Tim! Thanks, I have not tried the new Adder arm, not sure if it would fit in a Stinger. Steambow is going up to 150 lb now, so should have 35, 55, 90, 120, and 150 to choose from soon (no idea on final release date, but I got a pre-production 120 and 150 to test).
I am aware of the different positions on what to call the projectiles fired from crossbows, even reputable manufacturers cannot agree. Historically, many crossbow projectiles (bolts) had no vanes, and I have read this as a distinction between bolt and arrow from reputable sources. I have also seen people defining one or the other based on length. So I just say arrows most of the time (but never bolt for a vertical bow), and hope everyone knows what I mean 😀 And I heartily accept when people call them bolts or quarrels.
Many archers I talk to in the US call these short little projectiles for pistol crossbows darts... just to add to the "confusion".
What about accuracy at different ranges? I'm experimenting with carbon shafts and different weight bolts at the moment. Trying to get better accuracy with the stinger 2 tactical.. trigger is a disappointment and seriously considering filling the profile down a bit.
I am planning to do systematic accuracy testing on camera, walking back to see how far away I can hit a standard silhouette target. I want to use the 90lbs to get more distance, but also need to do something with the trigger first maybe. It works, but could be a lot better as you say.
@@fletchedevolution will be waiting impatiently for you to post that video 👍
great video👍🏽where do you get the NikA carbon Adder bolts with the big metal broadheads ? Cheers
I found some on Amazon (Germany) for a reasonable price, and just used some bodkin broadhead tips that Steambow sells. The same kinds of tips are usually available on Amazon and Ebay as well, and the Adder bolts I found use the same threading as all the arrows and bolts I use for standard compound bows and full-size crossbows.
@@fletchedevolution That's awesome thanks 🙏🏼 out of interest, have you looked into customising the Stinger with the 90lb limb doubled up with say the 35lb, or 2 x 55lbs for even more power ? I noticed a recent Steambow video where the CEO mentioned they are working on a 120lb limb wich he said is going well but no sign of it for sale yet?
@@moonshot1999 Yes, I shot a 90 lb plus a trimmed 55 lb (trimmed symmetrically to 27 cm with a small chop saw) for a while, and it was nice when I wanted that power. But only in a Survival, mostly using the cocking stirrup since cocking in the shoulder like I do with 55 or 90 on a "normal" Survival gets a bit painful after maybe 30 shots. I am testing the Steambow 120, a prototype of it at least, in a quick detach block and like it a lot. Very satisfying impacts and penetration, pushes their hybrid carbon/aluminum 162 grain blue bolts at 230 fps and the 232 grain bodkins at 200 fps.
I am also testing a 150 lb limb from them, but screwed into a standard mainfame since it is way too thick for the quick detach blocks. Not many shots with the 150 yet because the 120 is more important for their current pipeline, they told me.
Oh, I am also using their aluminum end caps on these, I would not trust the plastic jobbies for a high volume of shooting at 120 or 150 (my gut feeling). And I now only use carbon bolts (theirs, some from a guy named Torsten Baale in Germany (on ebay), or cheap Chinese ones off ebay or Amazon) at 120 lb or more. I have a box of trashed aluminum bolts from shooting too close or too hard of targets at 90 lbs, and more so at the 120 lbs I figure the paired up limbs gave me (feels about the same cocking as the 120 lb prototype, my bow scale only goes to like 80 or 90 pounds)
@@fletchedevolution Wow! TY for the comprehensive information 😎Very Cool ! The 120lb limb sounds ideal, while the 150lb sounds pretty crazy😂hear you on the bolts, I've got so many trashed using the 90lb limb, just ordered 100 of the new carbon blues, expensive though! thanks for the tips👍🏽
@@moonshot1999 No problem! Have fun!
What weight bolt do you recommend for the 90lb limb?
150 grains or heavier
Wieder ein interesantes Video von dir , mir haben die Schussdaten gefallen und den Unterschied zwischen 55 lbs und 90 lbs habe ich Kennen gelernt . Ich schieße zur Zeit in meiner Bude auf eine Stronghold Castle Wall und die ist 60x60x30 cm und die soll ausgelegt sein für meine JAG II . Mit dem 55 lbs gehen die Bolzen nur bis zur Hälfte rein und mit dem 90 lbs bis an die Vans , also kann ich die 90 lbs auf 10 Meter in der Bude Vergessen . Ich bin mit der Stinger II zufrieden und kann das Ding nur Empfehlen , ist für mich die Beste Pistolenarmbrust die es gibt .
Danke dir! Das Slydarc-Material stoppt 90 Pfund vor den Vanes auf 2 Meter, bei 120 tachen die Vanes ein paar mm noch rein. Auf 8 Meter sind schon ein paar Zentimeter noch frei vor den Vanes bei 120 Pfund. Super für Indoor und in verschiedenen Formen verfügbar. Aber teuer! Oder den Lappensack dicht gestopft. Ich teste jetzt ein McKenzie Speed Bag (ist ein Sack mit Polyesterwatte drinnen), und bei 90 Pfund auf 8 Meter verschwinden manche Bolzen drinnen, ist also da nicht geeignet. Die Stinger-Bolzen sind zu kurz.
Ja, für mich ist auch die Stinger die beste Pistolenarmbrust im Moment. Nach intensiven Tests mit meiner Vlad kann ich mich mit ihr im Vergleich zur Stinger nicht ganz anfreunden. Video dazu kommt bald!
@@fletchedevolution Danke dir für die Antwort , weil du gerade schreibst wegen der Polyesterwatte , mir ist da eine Idee gekommen . Ich arbeite in einer Fabrik an eine Presse , und wenn mit dem LKW Material angeliefert wird sind da grobe Gummistreifen drum und die Spanngurte vor dem Zerschneiden zu Schützen . Die Streifen sind ca. 10 cm breit 5mm dick und 20 cm lang , aber nichts hochfestes , muss ich Testen . Ich habe so ein paar Streifen daheim und den 3D-Drucker oder die Modellbaudrehbank etwas zu Dämpfen im Lärm . Was mir auch aufgefallen ist das es sich bei der Stinger II genau so verhält wie mit einer Feuerwaffe . Die V0 bei einer Feuerwaffe ist ja nur die Geschwindigkeit wo das Projektiel die Mündung vom Lauf verlässt . Das Projektil ist ja voll gepumpt mit Energie und wenn das projektil den Lauf verlassen hat hört die Reibung vom Lauf auf und das Projektil kann dann die Energie voll Nutzen . Ich hatte doch geschrieben das ich mal mit einem Bodkin auf eine Spanplatte geschossen hatte , die Entfernung war ca. 6 m , ich muss mal noch einen Opfern und das auf 10 m . Den Test mache ich mit den 55 lbs und 90 lbs , und jetzt bin ich gespannt . Wenn der 120 lbs bei Steambow raus kommt braucht sich diese nicht vor den Anderen zu Verstecken .
@@fletchedevolution ach so , ich muss mal die Matte auf ca. 6 m Testen weil du das sagst wegen den 8 m .
@@fletchedevolution noch etwas ich Schieße nicht auf Slydarc , meine Matten sind die , wie die Originalmatte von Steambow für knapp 60 Euro , also das Gummi und Kunststoffgemisch .
@@Hubimoser Ich habe jetzt einige der Hybrid-Bodkins bei ca. 0° Grad auf meinen Reinhart-Würfel geschossen, Distanz ca. 8 Meter. Zuggewicht 90 lb, Vlad. Das waren die von dem Test bei -13° auf den gefrorenen Slydarc. Manche sind jetzt leicht verbogen. Also sie halten nicht alles aus.
Den 120 lb finde ich wirklich geil, den Wurfarm kann ich auch immer noch im Anschlag spannen. Der macht fix Wumms! Aber dann müssen die Bolzen, die Distanz, und das Zielmedium passen.
Ich bin auf dein Ergebnisse gespannt!
What would be the maximum feet (distance) that a Bodkin/Broad Head bolt would penetrate a Human Skull using the 90 pound limb ? I am not really surprised but slightly disappointed the actual FPS stated by Steambow is in reality slower. But when you consider that with the 90 pound limb you get FPS speeds that are faster than just about any regular bow (recurve). As such hunting with the 90 pound limb on the Stinger II Tatical is more then enough FPS to take down just about any game that one would typically hunt for sport or survival.
I wonder if Steambow will ever come out with like a Stinger III with a reverse compound Head ? And would something like reach in reality FPS over 330 FPS you think ?
This is an odd initial question to be sure, given that zombies don't actually exist. How far it'd go through in practical terms is probably a moot point though, since both stingers can be lethal with whatever bolt when hits are to a critical spot. Maybe the zombie go boom channel will try that or something. A guy took some hogs with this thing (55 or 80lb limbs I think? he had the older model...) from a tree stand, and the hogs both fell quickly. The little broadhead didn't pass through like many archer's achieve with full sized arrows, but it did the job quickly. Anyway, it seems like your compact crossbow of choice (based on velocity specs) would be something more like the 328 FPS Cobra R-Series Siege Crossbow from Gogun.co and other places. With a 115-150lb adjustable draw resistance, it is bigger. It needs to be for that type of energy dump. It also costs double at about $600.
On velocities, keep in mind that Fletched Evolution did his test 6 feet away from the chronograph. The manufacturers are usually listing "muzzle" velocities so number can be compared, so the chronograph is probably as close to the barrel exit as possible when they test. They probably also do that since it is the highest number they can publish. Otherwise, they'd give you the numbers at the target just before impact and nobody would be impressed. You could probably do some math and figure out how much speed loss we should expect at 6 feet (or 2 yards) based of some generic factors. To me, this is not a disappointment at all! If they made a bow in this form factor with stronger limbs, I wouldn't want to have to try and cock it. Check out Joerg Sprave's Slingshot Channel and see why. He tried that already and it was too much for the stinger, especially the trigger setup.
Also, Fletched Evolution got as high as 208 FPS on the target dart with the 90 lbs. limbs. That is 95% of the manufacturer's stated speed at the crossbow exit point, and that was at about 2 yards away. So if it has only lost 5% speed after 2 yards and it is still accurate as claimed at distances of 20-25 yards, then this thing is a great compromise between portability, power, operability, and accuracy. Better for power and accuracy with the 90 lbs. and less on operability since it is harder to cock and shoot. The reverse would be true with the 55 lbs limbs. It just depends on what you expect to use it for and how far out you think you'll need it to reach to do it, but I am officially impressed.
@@a.j.7476 Well, as I was trying to find out on how close to a Human Head one would have to be using the 90 pound limb to have either the broad head bolt or the bodkin bolt be able to penetrate the human skull and into a person's brain. And yes I have noticed the increased trigger pull using the 90 pound limb versus the 55 pound limb on the Stinger II Tactical I own. You mention the "Siege" crossbow and yes that would do the trick most likely easily but then again it is much larger and heavier. Not so much a "tactical" weapon in regard to stealth.
I also own the Stinger II compact model and use the 55 pound limb on that. Though obviously the pull on that is quite difficult. The 35 pound limb is really useless for anything but target practice IMO. And one builds up the muscle over time to get use to the 55 pound on the compact more easily. Also a bodkin bolt shot into a person's skull (forehead) most likely would not kill them but definitely incapacitate them for a while where a shot using a broad head into the neck hitting the jugular vein would kill them. The head shot would be similar to a lobotomy most likely, haha. ANd then there is the shot using a broad head bolt to the back of the head just below the skull which could possibly sever the spine/vein causing instant death.
The obvious plus for using a Stinger II or even a weapon like the Siege is that one can get off another shot and another in a manner of seconds. Giving one an allowance to miss the mark on the first shot without failing to ... ;-)

I think the best way to realistically and cheaply test this would be to get some coconuts and start at say 20 meters/yards and walk the distance in. But I also think that no matter what you are shooting at, you are better off shooting at a soft spot. A practice bolt will penetrate up to about the end of the point/start of the shaft in a 1 inch spruce board at point blank range and 90 lbs draw weight. So call that 15 to 20 mm. Google tells me the average male skull thickness is 6.5 mm. But bone is also denser than spruce wood.
I think these bolts don't have enough mass or structural strength to get awesome penetration in hard targets even if you find a way to crank up the velocity. But I would like to see something like a Stinger III that is slightly larger with more poundage and a longer power stroke, but still not as large as a full-sized crossbow. I have tried the Adder and like the Stinger cocking solution much better. Reverse compound would also be interesting, though I prefer recurve especially for defense or survival ideas, since you can drop a recurve and whack things with it without as easily causing damage to the bow.
Enough poundage will give you 330 fps for sure, the Adder seems to top out at 270 fps at 130 lbs. But I wonder how easy and fast cocking a Stinger III with say 150 or 160 lbs would be.
Same System, 100 to 120 lbs, 1 inch more powerstroke, 1inch wider limbs, should reach 35 joules...
😮
I think a 90 pound laminated horsebow at a 30 inch draw could shoot 800 grains arrows probably 200-205 FPS. Same speed but much heavier projectile…. At the cost of much more skill and strength needed. Crossbow is better for home defense since it is compact and less stuff to carry. You may not have the dexterity in a heated situation to use a reg bow.
Yes, the power stroke on these kinds of compact crossbows is very short in comparison to a full size crossbow and especially to a vertical bow, and the power stroke plays a big role in kinetic energy.
Why nobody testing the 120lbs???
The repeater function is cool and handy as a self defense tool but for hunting it actually reduces the arrow speed and one shot should be enough from a tree stand or something. A horizone redback is way cheaper and is almost as powerful. Dont get me wrong i want a stinger but i cant afford one. I bought a pse viper years ago for $40.00 And a stinger 1 pro tuning #80 limb for $77 after shipping and taxes On a drunken binge impulse buy. Im pretty sure it could kill a coyote at 20 yards with a broadhead
But now for $117 i have a spare #50 limb and an extra string
Thanks for your excellent comment! I actually agree with you that a magazine is not all that attractive for a bow hunting situation. It should be one and done, like millions of hunters do with bows every year. Especially at 90 lbs, the power is there for sure if the game or varmint is not too large and the hit is good. These videos have been skewed to hunting since Steambow asked me to evaluate that specifically, and I like shooting at hunting-type targets in the woods since I love to hunt. But I also think these magazine bows are really more interesting for self defense (aside from the fun of plinking and target shooting) if you do not have access to a firearm, or do not want to use a firearm for whatever reason.
@@fletchedevolution What was the "trigger pull" like with the 90lb limb? Was is uncomfortable, or was it just bearable?
@@cunnyfred9562 Very heavy, but also totally doable if you have good trigger control.
What do people hunt with this crossbow?
A couple young wild hogs have been taken, one on RUclips video (Keith Warren), but that is too large in my opinion. Rabbits, squirrels, grouse would be it in my book.
Ok thanks very much for your comment
Weird because I also weighed the bolts and got different numbers than you
Interesting, can you elaborate? Heavier or lighter on average, more or less standard deviation and extreme spread? What kind of scale did you use? I wonder if there are significant variations between bolt lots from them over time.
@@fletchedevolution for the practice I had an average of 142 grains, the bodkins an average of 167 grains and the broadheads 154 grains I just used a cheap digital scale, maybe my scale is off and I didn't have as many bolts as you, just weighed each pack that I got
@@fletchedevolution also when I weighed them I calibrated a can on top to prevent the bolts from rolling around
