    First of all, I want to say I am so happy to see new content on this channel. Ted is a top-notch marksman and I have enjoyed these videos for years. Regarding the BC - why not put another chronograph at 100 yards and measure that velocity compared to muzzle velocity and calculate BC that way.

    I believe you found the perfect speed and twist rate for that specific lenght and weight over that specific distance. In other words, the slug flies true through the trajectory curve for perfect aerodynamic angle of attack. No nose up or down during the flight through the trajectory curve. Just perfect. The choke of the barrel will also play a big role here on how it releases that slug (angle of attack). It's like finding a needle in a haystack, possible but very rare. Good football quarterbacks have the ability to throw, release and spin the football just right to achieve perfect angle of attack, speed and twist for optimal flight in order to achieve maximum distance with the least effort. Everyone who has thrown a football enough has at some point found that "feeling" of a perfect release. This is very difficult to achieve with a barrel in a gun. I believe you have found your unicorn.

    As an old high power rifle competitor, 200 to 600yds and 1000 yards. I am enjoying seeing you go thru the exact same testing to achieve the best accuracy you can from your equipment in an air rifle. Your finding that a pellet dia. in ten thousands of an inch can make such a huge difference in performance. My shooting was 50 years ago, and I heard of some top shooters that would go to the sierra factory and mic bullets coming out of the bullet making machine until the die wore down enough to get the dia they wanted and then take the next ten or twenty thousand bullets for reloading because that dia is what their barrel liked.

    Hi Ted. I just tested this with my LabRadar. I used the same barrel, 800mm 1:14 twist and same slugs, NSA 31.2gr .2165 . I shot a 15 shot string at 100yd. Average muzzle velocity was 1,087 and average velocity at 100yds was 941. Taking air temperature, station pressure, and humidity into account I got a G1 BC of .132. RA4 BC was .104.

    More Spin, Less Drag
    In this article, we look at how twist rate and stability affect the Ballistic Coefficient (BC) of a bullet. Again, this topic is covered in detail in the Modern Advancements book. Through our testing, we’ve learned that adequate spin-stabilization is important to achieving the best BC (and lowest drag). In other words, if you don’t spin your bullets fast enough (with sufficient twist rate), the BC of your bullets may be less than optimal. That means, in practical terms, that your bullets drop more quickly and deflect more in the wind (other factors being equal). Spin your bullets faster, and you can optimize your BC for best performance.
    I think what you're seeing is your finding the sweet spot of the spin rate, ,this increased the BC which effectively increased the accuracy for longer ranges. I would almost guess the bullet as two sweet spots one low at the smaller BC and the one you have found...

    • @mikecollins8241
      @mikecollins8241 Год назад +1

      I agree: it would make sense that a higher initial velocity, and greater rate of spin, would ccause more "lift" from spin "traction" as the bullet bites it's way thru the air. I love this stuff, as I've been an avid handloader for years, and the mysteries keep coming! "What we THINK we know, vs What we find in testing"

    • @kwk8363

At 1100 fps(about mach 0.97 drag on projectile at the muzzle is so much higher than subsonic speeds and its nothing to with spin rate or even type of the projectile (bullet,slug, airplane!....)what you saying could be true in supersonic projectiles like canterfire rifle bullets,but here we are dealing with subsonic airgun projectiles, clearly something is going on in this case,but as ted says, it must be impossible!!

  • @RyeOnHam
    @RyeOnHam Год назад +12

    Internal ballistics are a funny thing. Barrel whip can throw the same bullet to two sweet spots at different velocities. The first (lower velocity) shot may be whipping the muzzle down slightly and giving you a stable muzzle exit at with the muzzle low. The higher velocity may be throwing your groups higher. This gives you a different number to calculate BC than the 'accurate' number. You'd have to check velocity at multiple points on the trajectory and see if the velocity is dropping with the BC.
    The other alternative is that the BC is changing due to transonic interactions with your bullet profile. Bullets do weird things whey they try to push air around them at supersonic speeds, even though the bullet itself isn't supersonic. You could be getting a better BC because of the supersonic flow characteristics of this particular profile. Me, I avoid transonic as much as I can. With my .44 Magnum rifle loads, I stay at about 1,050 FPS. Bullets that fly much faster risk running into weird stuff, as you may have experienced. Only strike against this theory with your bullets is that they slow down REALLY quick to full subsonic flow.

    BC is defined by change in velocity between 50 and 100 yards. Delta in POI could be deceptive because it includes the effect of barrel harmonics.

  • @stevegray4012
    @stevegray4012 8 месяцев назад +1

    Hi Ted, First off I'm no mathematician but you might be forgetting about the angle change when zeroing, At the lower velocity you tilt the barrel higher to compensate for the distance to zero (50yds) if the velocity increases that angle changes to hit the 50 yds zero. I put your data into the Hornady calculator, here's what it says.
    1000fps, BC 0.09, 26gn projectile, scope 3.75" above the bore, 0yds= -3.8", 25yds = -0.6", 50yds = 0", 75yds =-2" 100yds =-6.9".
    1100fps, BC 0.18, 26gn projectile, scope 3.75" above the bore, 0yds= -3.8", 25yds = -0.9", 50yds = 0", 75yds = -1.2" 100yds = -4.5".
    1100fps, BC 0.09, 26gn projectile, scope 3.75" above the bore, 0yds= -3.8", 25yds = -0.8", 50yds = 0" , 75yds = -1.5", 100yds = -5.5.
    I read somewhere that the location of the scopes reticle adjustment relative to the triangle created by the barrel and scope axis relative to the projectile start point will make a difference in the amount of clicks needed to reach zero (ATN web site I think), your rifle has the projectile a long way behind the scope reticle adjustments, in other words your adjustments are having a greater effect than if the projectile was below them

    I've also ran into many ballistic "mysteries" but in the end they were simply not taking into account of atmosphere conditions or user error. Temperature and altitude density have HUGE affect on BC/trajectory. Zero one day and not readjust to new weather condition into the ballistic calculation will through you off big time. I've learned the hard way and always validate zero and reset atmosphere conditions in ballistic solver with minimum local weather station information, I try use a weather meter for my ballistic solver and make a point to update the information EVERY HOUR!

    For those looking to get the .2165's, keep in mind that the performance here is specific to his setup. Each gun has it's own personality so to speak and what works incredibly well in one will not work as well in another. Replacing a worn-out barrel or regulator, etc can and will affect performance with any load.
    You also need to consider lot number. For example, my M24 clone shot the first lot of Federal SMK BHTP 168 gr at an incredible 1/3 MOA. When I moved to a different lot of the same load the groups opened up to 3/4 MOA.
    So, definitely consider the load(s) Ted is recommending, but YMMV.

    Hi Ted, great info on the airgun and new slugs. That is pretty cool what you are getting with these slugs! I had one thought which is - why introduce the scope change into your calculation? Simply shoot at 50 yards and it impacts the target, you can make it near zero but quite honestly it does not destroy the point of aim if it hits a few inches low. Then simply back the target up, continue to shoot at the same aiming point. Measure the difference between the two groups and you have the drop at 100 yards. The aiming point is quite irrelevant so long as the aiming point is the same each distance, I actually prefer to make a cross with a heavy marker or even tape depending on what I am doing. That way no scope calibration issues are introduced, etc. The drop is what the drop is. Just have to shoot at the same point, leave the scope alone. Keep on killing those starlings!

    The air bubble on/in the HP is trapped creating a "tip" on the slug. The higher the velocity the more efficient it becomes because the air bubble is under more pressure from the on coming air. This in turn lowers the resistance the actual slug is facing because of the twirling air inside the HP is under more pressure getting push through the atmosphere by the slug.
    High powered rifles used for competition shooting use hpbt and not pbt rounds for this reason.
    How fast is to fast before this has diminished returns? I don't know but with pcp's it doesn't matter but clearly you have just proven that this effect starts to really have benefits around 1100fps and not so much below 1000fps.

    Rotation of the slug makes the air travel a longer distance along it. This would make the slug virtually longer. With 335m/s the slug should rotate about 20k times per minute.

    Amazing Ted! Would be interesting to try another barrel (the same) and see if you get the same results🤔 This would then show you have found your nirvana combination. Also cleaning the barrel to see how that affects your groups. It is amazing how far air rifle technology has come in a few years! Great video!

    First let me say Ted, I love your channel/ posts, Keep it up. Thank you.
    This is a great example that shows that BC is not a constant as is too often believed. This might be an example of better stability. or I will have to refer to the boys at Sierra bullets. Sorry I cant put it into words but give them a call they will explain this very well, how or why BC IS dependent on Velocity. There are computer simulations that show what the air does around a projectile in flight at differing velocities I just can not find one right now to refer you too.

  • @mattstrohmeyer5839
    @mattstrohmeyer5839 Год назад +4

    Probably the same concept like an arrow flying. You perfectly found the speed needed to stabilize the slug in the air. When a arrow is shot at a slow speed the fletchings need to be larger to get the same bite as the smaller fletchings at a higher speed. Like a fighter jet. They use 100% power as slow speeds because they are falling from the sky. When they actually get to optimum flying speed they stabilize. I'm pretty sure that's what you are witnessing with your slugs.

    • @JM10344

    • @le3045acp
      @le3045acp Год назад +1

      to a point but if the bow is correctly tuned the arrow will fly straight with no fletchings in other words the only thing on the shaft is a nock and a field point and no fletchings that is the correct way to tune a recurve or longbow it must be in harmony

  • @precisionairguns5553
    @precisionairguns5553 Год назад +2

    Here is the response I put up on my group Precision Airgunning
    So, does anybody want the answer and explanation? Its really quite simple!
    Ok So, Teds theory of a .22 calibre 30 grain slug with a manufactures published BC of 0.095 having a BC of 0.180 is not only wrong, but absolutely bonkers. So lets start with some basic ballistics. Using a G1 standard BC drag models the BC is not fixed, it is in fact dynamic and changes with velocity and bracketed into velocity bounded segments. BC is normally the first thing an inexperienced user/shooter will manipulate, mainly because its the one thing that they least understand. I mean people find comfort in that they believe their velocity is 100% correct because their chronograph tells them so, we wont go into chronograph read error in this subject but just keep in mind that it does exist! A few other things to keep in mind on this sort of situation is - Range error, velocity error, environmentals, false zero and scope tracking error, to name a few, they all exist. Anyway moving onto the mysterious issue that has got all the top dogs confused! In shot ill just go out ad say it - Scope height, yes it is that simple folks an here is why. If you look firstly at Ted's Rifle set up he has a Saber Tactical back bone rail with inbuilt 20/30 MOA built in, some sort of scope base with built in adjustable elevation,, scope mounts and then the scope, just look at the scope height its crazy high. Then move over onto his Chairgun Pro data where his inputted data states that his scope height is 3.75",crazy high! Essentially what this is causing is excessive or an acute angle with regards to line of sight relevant to bore line. So some more basics, when any projectile leaves the bore regardless of velocity (500 - 4000fps for example) the projectile slows down and and begins to fall away from the line of sight (Gravity) immediately and continues to do so. So how do we hit targets at 100,200,500,1000 yards away, well we add trajectory into the equation via the scope, effectively adding ark into the equation, or lobbing bullets in laymen talk. So in order to order to hit a target at distance the projectile has to leave the barrel and leave the bore line to meet or match the line of sight, (primary (1st) or secondary (2nd) zero) With airguns, because generally they are used at closer ranges when compared to long range centre fire rifles we have to be a little more, lets call it aggressive with the angle created through our scopes in order to match our POA vs POI. This only seems to effect airguns, largely because of what I said above and their close range usage. Im sure some of you guys who shoot either sub 12ftlb air rifles, or a better example is night shooting close range rats at say 20 yards with a perfect 20 yard zero, notice how if you aim directly at a 30 - 40 yard rat you will shoot clearly over the top of it, but then a 50 -60 yard rat you can aim straight at it and hit it, this is the primary (Close) and secondary (far) zeros \I was talking about before. In Ted's situation he has come across the exact same problem but at just a further distance out, this is due to his excessively high rifle scope. To meet his 50 yard zero he will have to have some serious angle dialled to mach his POI vs POI. Once he shoots and hits his zero at 50 yards, the slug, particularly at higher speed will shoot through the line if sight and continue on its upward path above the line of sight to around 70 yards before coming back down through the line of sight back town to his distance of 100 yards. this gives the impression that the projectile is shooting flatter when it is not, its just got a greater arch due to the excessive built in scope height. I hope I have explained it in a way that it can be understood, ill add some Strelok screen shots to demonstrate that just by changing scope height can manipulate the POI down range. Ted simply has just hugely manipulated the BC value of the projectile to the point that it matched his real world DOPE - wrong on every level! I hope this clears this mystery up, just take note that we can simply explain Ted’s findings by simply matching his Correct scope hight and manipulating various scope hight settings to vary results and not BC, if you take one thing from this, make sure you pay attention to scope hight!

    • @Justin-nx5ou
      @Justin-nx5ou Год назад

      You can get the same results by slightly altering far zero. Also when he shot his 50 yard shot after dialing 5moa for 100, his shot at 50 is exactly 5moa high.

    Hi Ted. Great video as always.
    Is it possible that with the change in velocity that your barrel is vibrating differently and the slugs are exiting while your muzzle is pointing higher?
    Sidenote: You could verify if the BC is actually increasing if you had another chronograph at your target to measure the velocity at 100 yards.
    Thanks!

    I only shoot pellets, but I still adjust my BC to get it spot on. And I have yet to find a manufacturer BC that's actually perfect. And the BC I end up with after shooting/testing a pellet is always lower than what they say!
    The actual BC number is kinda weird to me because just to change the POI an inch at 100 changes the BC number a lot! But I don't really care what the number is, or how my BC compares to the one given by the manufacturer... all I care about is that it's correct for me!
