Here is a little problem for you gear heads to (re)calculate. If my figures are correct, the bullet (at the weight, velocity, BC, scope height & preset, etc.) wouldn't travel that far, unless he was atop a tall building!

My calculator shows a maximum range of 2692 yds. at a 36 deg. angle at sea level.... At the 7800 ft. altitude he was shooting at, that increases to 3301 yds. at a 38 deg. angle.... Those are using the (correct) G1 drag model.... I have no idea how you would include his scope height into those calculations, or whether that would make a difference in the maximum range.... I rather doubt it would matter, as the barrel elevation from horizontal is the governing factor....

I hope I didn't imply that....

The scope settings would aim the bullet too low. Like I said, I hope I didn't mis calculate.

Sorry, Alan, I misunderstood you.... Yes, his calculations are off by about 40 MOA (roughly 40 feet or 500 inches) at 1100 yds.... The bullets would not have reached the target if he simply clicked and shot, IMO....

I think the fact David has not responded to this thread shows he sees how he screwed up.  There is no way to defend it - it is all in black and white.  I will still test the bullets for their BC when I get them and borrow a .308 rifle to test in.

 Nick How much FPE do you need to test them? I have a 308 but maxes out around 220 fpe. No where near the 332 claimed output  of said Texan.

Those are pretty heavy bullets.  220 fpe for those bullets is around 800 fps.  To be honest, I already know the results, or at least the rough numbers.

In my opinion 800 fps would be fine because we are talking about a discrepancy of huge proportions.  He could argue that the results would be different at 150 fps higher velocity but we are talking about twice the BC not a 10% difference.

David

dont worry its impossible to hit a pdog at 84 yards and kill it with a 177 break barrel gamo.  84yardsmyass right grumpy lol.  Hey the shooting gods were in your favor and doubters will always doubt. 
I suggest a video for proof since obviously pictures can lie.  or so im told

I received the bullets today in the mail and I am leaving to go hunting in the morning.  I have a .308 Slayer to bring with me so I will do my best to do the BC testing with the Labradar and report back early next week.

If you follow what David wrote and how he came to his numbers after zeroing in at 100 yards and then simply clicking the MOA and hitting the target 3 out of 4 times it is impossible based on the numbers he used.  He used the wrong BC for the calculation used, or you could word it that he used the wrong calculation for the correct BC.  Either way, no way possible what he claims is true.

No doubt an air gun can reach out to 1100 yards, Carl has been past it.  There is no way David did it as he explained it, or, he did not do it at all.

Well if he has the MOA in the scope mounts that it looks like he has, then there is no way he can zero at 100 yards than click out to 1100 yards. Just not enough clicks in the scope.

David said he has the Cold Shot 300 moa scope mount rail.......I used  that too and for my last video of last year I used 298 moa or close to it to get to 1108 yds and be right on middle crosshairs in scope....I had more mil dots and 25 moa i scope available if needed............He had the necessary equipment to get elevation.. Using a G7 model for the .271 BC he relies on is flat wrong, or numbers that model gave him. I will tell you having calculated MY OWN BC ###'s shooting thru 2 Chrony's at same time, even then those bc TEND TO BE SHORT in moa needed the further  distance shot.  2 1/2 yrs of constant airgun and cast lead bullets I CAST, shot at distances in 100 yd intervals to 1108 yds, I will guarantee the bullet he is shooting has no better flight characteristics than ones i did shoot. Except the fact it is heavier and that does help to a point but it will slow down over that distance by 400-500 fps and that is where he doesn't get it.......May be and probably is for his BBL a good bullet but has no magic qualities. Nick will have Lab Radar ## soon

Wow.  A lot of reading.  I am not offering to get between the dogs peeing on this tree but I do remember one of the earlier statements of "This isn't going to end well.  I think that was about the only thing that couldn't be argued.  I'm going back on to view more videos.  More fun.

I shot the Hunter Supply bullet this weekend.  I shot it in a Slayer with the same twist barrel with a different tune that Texan but close enough for sure.  I am going to post the data here and I am sure Bob will do the honors.  I did not have internet, or even text, over the weekend where we were hunting so I have not calculated it yet but I did get an idea of roughly where it is. 

So I only recorded 6 shots because they were so close I knew they are good numbers and the BC testing we are doing is to see if the bullet is a magnitude better than all the other bullets on the market, not to get a BC that we can use to calculate drop and moa with.  I did take more shots than what I recorded and they were all the same fps loss from muzzle to 50 yards.

Muzzle/50 yard fps     fps loss
691/674          17
704/683          21
696/677          19
688/664          24
686/666          22
688/665          23

 Nick first thank you for taking your valuable time and expense to clarify this. Second that Slayer has some serious power for a bullpup! Third I hope the youtube claims and facebook claims are removed now as I feel that Rifle50 at this point STILL has the world record and this should be justified. I dont think anything else I would post would be of much use so I will leave it at that. Nick I assume this was done with your Lab Radar?
