Looks like my shooting setup during the summer out here in Texas...too many burning hot days. Dont forget to pack up the gazebo like I did. A little wind overnight and I found the gazebo destroyed on the other side of the field the next morning. Thanks for the video.
Yes... this is my NEW gazebo, not my first gazebo hahaha the exact same thing happened to me lol my first one got properly destroyed in a nasty little storm
Thanks for your suffering in providing that comparison. It’s bloody hot in Queensland at the moment. Don’t own a pcp but try to keep up with what’s going on. My springers will do for the moment Great channel, keep up the good work.
Mark the liners top before you remove it so you can put it in at the same place again ! Try fire 5 round and twist the liner 1/4 turn and you hitpoint will shift ! Turn 1/4 again and again until your hitting the highest point on the target ! Mark the liner at that point ! Now you got a straigt shooting rifle .
Keep us all updated please. Im trying to figure out wich is more acurate my self. I have a .25 shooting at about 877, trigger on C and valve at second line with 125 bar. Gun is Fx mk2 power plenum. I been shooting at 94 yards about 10 tins of jsb heavy mkii 33 grain out of the stock twist liner gun came with. Ok results not particular satisfied. Since your video I took out my slug liner last night i had bought while back cause i been wondering if slug liner is more acurate myself. Took it out today and for 3-4 shots it hit nearly perfect untill wind took me out of testing. Ill have to continue tommorrow on the test. Hopefully not a fluk. It would be interesting if slug liner indeed is more acurate. Would be disapointed on the pellet twsit barel.
Do you think that the big POI shift could be due to a slight bend in one of the barrel liners? I’ve also experienced a big POI shift by over tightening the nut. It would be interesting to test how straight FX gets those liners by shooting a few sets of groups with the liner indexed in different positions. P.s. you’re the man 🤙
I think I will do that just to get maximum elevation possible... Id like to get some elevation in my optics rail and scope mounts and have my scope closer to the bottom of its travel
Slug liner vs pellet liner shooting pellets... I've noticed a difference in POI using the same liner depending on liner positioning (different reference point of liner rotation). I haven't had the time to do in depth testing but I've noticed quite a difference in POI. I am curious as to how big a difference there is when I change out the whole barrel kit. Testing to come soon as I will have more time on my hands in the near future. Maybe a good start up video for my (hopefully) coming channel . Great stuff on your videos. Look forward to more
best way to start a channel is just to start any way you can, your first few videos are probably gunna be terrible no matter what until you learn your style, just delete them once you look back and see they dont fit with the new stuff lol
Awesome video! Loved the experiment. Liked and subscribed. It appears that the barrel harmonics and twist cause a helix trajectory that crosses perpendicular at 50 meters at approximately 10 inches and at 5 o'clock because the group is way to small, so I suggest the same setup and shooting 20 shots at every 10 meters to make the experiment statistically significant and reproducible at the 95% level. Its almost akin to bowling where the spin, trajectory of the ball travels across the lane and crosses the center of the lane at the end of the lane to get a strike.
This is my view on pellets from the slug liners. I have a dreamline with .25 slug and pellet liner and a .22 600 barrel kit with slug liner and pellet liner. I mostly use the .22 setup right now. At 50 yards the slug liner works fine for pellets at 100 yards slugs have a huge advantage so I dont shoot at 100 with pellets. Slugs for long range pellets for short range. Currently I'm shooting .22 24gn dish back slugs a 880 fps with a bc. Of .081. The difference is 41 FPE at point blank and 30 FPE at 100 yards compared to a jsb 18.13gn at 31 FPE at point blank and 14 FPE at 100 yards. I would have done this in .25 as well but the fx .25 slug liners I have used dont like .25 slugs they seem to be to tight in the barrel. I'm waiting to try some .249 slugs to test more with the .25. Anyway that's my 2 cence great video keep it up!
@@meatheadmarksman2013 well I'm about to find out we just got our .249 die last night as soon as the sun comes up I'll start testing. I have high Hopes after pushing a slug through the barrel, the interaction felt much better. My comparison is based on the way the .217&.218 slug felt when pushed through. I got better results from the .218 by just a little bit. The .25 was very tight in comparison. The .249 felt very similar to the .218. If I have time I'll make a video today. This winter my uncle is getting a business license to sell slugs internationally. Oh yeah all my testing at the moment is with a fx dreamline .25 (600) and .22(600) as well my uncles impact and crown in every caliber but .30
@@meatheadmarksman2013 fisrt tests in .249 are holding about 1/4 inch to 1/2 inch groups at 50 yards wich is way better then a .25 holding 2-5 inch group at 50. Already got rid of a few bird feeder bullies this morning. 100 yards coming up lol. Happy shooting love your videos
Good stuff. Just add a little information. With a slug liners you may want test multiple distances. if i remember currectly they shoot well with any pallets compare to STX A liners only shoot JSB. but some point of far distances, a group start opens and pallets destabilise because slug liner is a little bigger then STX liners and spin faster. I would like to see how much different between the distance that effect shots.
I purchased the Kervan Airboss K1 25 cal. I would like to shoot both slugs and pellets. In order for me to do this do I need to change to a different liner? Or do I just have to experiment? The ideal barrel from what I understand would be the FX smooth twist, superior X barrel I have not polished the barrel yet.
Just a guess : there may be a difference between the internal diameter, which would explain the huge difference in impact shift ? And, many thanks for your video's they are pleasant to watch.
@@meatheadmarksman2013 The impact shift between the rotation of the liner, on the video I've seen, was just about 2-3 cm at 50m, not more. Here the difference is really huge. Actually the .25 slug liners are not available (all sold) here, but that's my next buy for sure. If I'm able to (double) fine tune the gun with pellets and slugs with the same barrel, that would be marvelous.
@@MartinGoblet-be I rekon its doable if you run heavy long pellets for sure. tune your max setting for the slugs and just use whatever lower power works best for the pellets. should be sweet as
Depends on what becomes available domestically mate. I suspect h&n slugs will be the only real option for a while once they send a shipment out way, the other companies have said they are keen to brake into the Australian market but I havnt seen anyone stock them yet
If I were you I would try the mark ones and maybe turn it down a bit I guarantee those groups will get tighter. I have mine shooting around 880 and I’m getting half inch groups with the mark ones and I’m just a tad bit bigger with the mark 2 use in the slug barrel
I think there is an accuracy node around 880fps, my crown was shooting nice groups around that speed. There are other factors at play at my place but, it's almost impossible to read the wind properly here, even at 50m I'm shooting through 2 different directions of swirling wind haha
Thanks man I’m just about to do a new order on some bullets and I want to try something different I’ve only used the JSB heavies I made the foolish mistake of buying 30 packets at once 🙄🙄

very good groups , if the power level is not a issue, you can shoot with a weihrauch hw 30s .(10 joules)177 the same group at 50 meters ,shot wit jsb exact express diabolo ,if its not to windy. i think all those liners and possibility`s will make you confused, i would go for a bull barrel thats groups a 100 meter. , then you do not have to deal with tensions and settings of the same liner to find out the the group moves or changes
I like having specialist options, I really enjoy the tuning and tweaking and finagling, it doesn't confuse me at all but I see how it could be a hard hill to climb for someone who is not committed to learning about ballistics.

Wouldnt have a clue mate! Nobody tells me nothin... the only slugs I have laid eyes on where the .22 grizzlys from h&n and theyre no good to me cos theyre not in 25!
I'm already getting 935fps with heavy 25 cal, I personally don't need any more power. My dad has a mki impact that might benefit from a power upgrade...
@@meatheadmarksman2013 yep, clear but shooting at 110bar those heavies is so much better than going 140 or 150bar and the shot count is biger 💪💪💪 If you would like, I can send you one for teting it ... lets see how you like it.
@@vladankrosaki I'm always keen to try new things! Send me a message on instagram @unclehodge or on the meathead marksman Facebook page. Might have to be off in the future a bit, all my money is going into fixing my car atm
Would it be better to shoot the pellets at a lower power so they’re not being forced as much as what you need for slugs? Interesting video as always my friend from down under 👏👏👏👍 I’m guessing if turned down to say half or one of the side powers (a,b,c,d,e) would help with pellets 🤷♂️🤔
Perhaps, I'm not currently tuned for slugs I'm tuned for that specific pellet. I think given a few more pellets through that liner it would settle down and be very accurate
Meathead Marksman just waiting to hear back from the firearms department about my FAC which is needed for over 12 ftlb over here. It was a toss up between the impact and crown. I love the look and feel of the crown but the impact is so much more fine tuneable,,,, so it’ll be the impact 👍. I’ll be using slugs for my longer range rabbit (pest) control. Pellets on min settings though the slug liner, so this video is one of those that was very interesting to me as I don’t want to keep changing liners over. Hopefully you’ll work out the best way to get the liner being perfect for both slugs and pellets 👍
@@peewee007654321 I rekon if you tune your max setting for your heaviest slug then the rest of your lighter pellets and slugs will work well somewhere lower on the hammer spring wheel. Mine certainly does
If you would’ve turned the pellet liner a quarter of a turn clockwise if you’re looking down the exit end of the barrel it would’ve brought your point of a aim up 👍🏼
Hey Unc’. The POI shift is probably due to liner orientation. They’re not straight mate! But you knew the didn’t you? You did though, you knew....... 👍 I’m also thinking 930 might be a little fast for diabolo pellets. I’ve just sent you a picture of a group I shot on Wednesday evening on Instagram. Velocity was 890 FPS with King Heavy Mk 11s. I want my 60 foot pound air rifle to match what I had with 12 foot pounds at 50 metres, pinky nail size groups, else what’s the point? Great video again mate, but those groups? I’d want more........Slow the velocity a touch and prepare to be amazed. Also, do what the other guy said, turn the liner a touch after each shot until you get the 12 o’clock. Shot, then mark the top of the liner. Do it on every liner you have. No more poi shift. I’m off to watch your twist rate vid. Cheers.
I knew about the orientation thing (because I always forget to mark the liner before I take it out lol) but I didnt know it was because there not stright haha Its a 1 hole group at 50m with the pellet liner so theres no stability/grouping issues at 930-940fps for my gun. Ive seen a few people actually push them right up to 1000fps with remarkable accuracy, but that would be getting way too loud for my taste
Meathead Marksman Mine won’t go as high as 930 😔. But today I got it running at 904 average for 62 fpe. That’s maxed right out! I’ll try it on Monday on my shooting permission but I’m not hopeful. I shot it there yesterday with the same settings as in the pic I sent you. Groups opened up to 20 mm at 75 yards. At 100 yards......well, I wouldn’t describe the shot pattern as even a group. I’ve got a slug liner but I don’t think the mk1 impact can generated the power needed for the slugs, I chronograph mine at 780 FPS with 34 grain slugs with everything maxed out, it was hopeless. Did you chrono the slugs? If you did, what was their velocity?
@@pestandwildlifecontractser5589 I havnt shot any slugs through mine yet as theyre not commonly available in australia, you can get them from the states but its a giant pita. waiting for australian dealers to pick them up. are you running a 700mm barrel or a short one?
Meathead Marksman Mines a 700mm Mk1, a late Mk1......just before they brought the Mk11 out, so the plenum is the smaller capacity one and I think that’s the limiting factor, but then bigger plenum needs heavier hammer, heavier hammer need different spring, more air needs modified ports blah blah blah....There’s a chap lives not 200 metres from me doing power kits for Impacts, he’s on Instagram, I’ll send the link later. At near 200 quid plus his labour though, I maybe need to be happier with what mines doing. Can you not get slugs at Krale in the Netherlands? Not sure how long they’d take to get to you.
@@pestandwildlifecontractser5589 Hey if its working well for ya I say don't upgrade! thats one thing I try and hammer home (pun FULLY intended lol) every time I talk about this sort of thing, theres always another upgrade, a bigger slug, a longer barrel, a better twist rate but if you don't need it you really have to make sure you know WHY you WANT it. If its stacking pellets/slugs with enough killing power at your preferred range then I say leave it alone unless its just for the sake of owning something tricked out - which I am also cool with haha

I shot it there yesterday with the same settings as in the pic I sent you. Groups opened up to 20 mm at 75 yards. At 100 yards......well, I wouldn’t describe the shot pattern as even a group. I’ve got a slug liner but I don’t think the mk1 impact can generated the power needed for the slugs, I chronograph mine at 780 FPS with 34 grain slugs with everything maxed out, it was hopeless. Did you chrono the slugs? If you did, what was their velocity?
@@pestandwildlifecontractser5589 I havnt shot any slugs through mine yet as theyre not commonly available in australia, you can get them from the states but its a giant pita. waiting for australian dealers to pick them up. are you running a 700mm barrel or a short one?
Meathead Marksman Mines a 700mm Mk1, a late Mk1......just before they brought the Mk11 out, so the plenum is the smaller capacity one and I think that’s the limiting factor, but then bigger plenum needs heavier hammer, heavier hammer need different spring, more air needs modified ports blah blah blah....There’s a chap lives not 200 metres from me doing power kits for Impacts, he’s on Instagram, I’ll send the link later. At near 200 quid plus his labour though, I maybe need to be happier with what mines doing. Can you not get slugs at Krale in the Netherlands? Not sure how long they’d take to get to you.
@@pestandwildlifecontractser5589 Hey if its working well for ya I say don't upgrade! thats one thing I try and hammer home (pun FULLY intended lol) every time I talk about this sort of thing, theres always another upgrade, a bigger slug, a longer barrel, a better twist rate but if you don't need it you really have to make sure you know WHY you WANT it. If its stacking pellets/slugs with enough killing power at your preferred range then I say leave it alone unless its just for the sake of owning something tricked out - which I am also cool with haha
