If I had made these shots and had it in video I would have posted it. And I would have not been impressed with anyone playing it down. I have seen first hand what two different LRKM's can do at past 2500 yards. Now 3600 is a heck of a lot farther, but 1 moa consistency at 2500~2700 yards is reality for the LRKM and Shawn's video at 2751 shows 3/4 moa hits. Some think as soon as you go subsonic the game is over. I am here to tell you first hand that is not true with all bullets and altitudes. So it is coming boys like it or not.
Just my take on all this.
From what I have seen with the testing I have done with the 300 gr SMK and the prototype 265 gr AT RBBT, as long as velocity remains at or over supersonic velocity, sub 1 moa is easy out to the limits of this velocity range. As mentioned, I have tested the old, unsexy 300 SMK out to its limits, which are around 2900 yards or a bit more out of the AM with steller consistency and that projectile is totally predictable out to that range.
The 265 gr prototype was the same way out to 3010 yards but I was not able to test farther then this to see if it had any more legs which I am sure it did. From drop numbers at 1000, 1500 and 2000 yards, the BC came out to around .9 to .92 depending on the day shooting. Now, that is the number I needed to put into the program to get predicted flight trajectory to match up with actual bullet trajectory so I am not saying that was the SCIENTIFIC BC value of that bullet before someone gets pinched in the shorts.
Combining that with the 3550 fps and you get something pretty special. That was with Jamison cases, with the new Bertram brass, well over 3600 fps would have been practical with good brass life. To bad we do not have those bullets still, life goes on.
I did not test them at 2 miles for one reason, ran out of supply and Wildcat Bullets sold to a new owner.
I have yet to see a quality rifle not hold at or under 1 moa for grouping out to the limits of the combos supersonic velocity range. Bullet needs to be properly stabilized but if that happens, I have never seen a consistency problem that kept groups out of the 1 moa size.
That said, please realize that I am not saying that shooting conditions will not limit your ability to hold 1 moa groups at extreme range. When I was testing at 3010 yards, I did so on 6 different shooting sessions. Two of which I was able to put three shots in a row on my 20" round gong. On one occasion, I went 2 for 3 on steel. On three other occasions, because of wind, mirage or simply air conditions of my lack of shooting ability that day, I did not get a bullet on target. There are days, I am just not up to it!!!
Still, even on those bad days, missed were well under 2 moa in total size.
THis was +600 yards closer then the target in the video. Still, I would have to see this with my own eyes to believe it and even if it did, getting two shots BARELY on a 12'x12' target is hardly precision shooting in my opinion. I believe they were happy with the results because that's the best that could be hoped for with that combo. If they were maintaining supersonic velocity to that range, they should have been able to at least gets shots consistently on that size of a target with no problem. If they were using a bullet that was handling the transonic velocities well, again, it should not have been a problem to get bullets on that size of a target.
I suspect they were doing neither and as such, barely got a couple shots on the fringes just by chance. Would like to know how many shots were taken to get that snippet of video? That's the bad thing about the web, anything can be made to look like anything as there is very little accountability out there when you post something on the web other then your own principles. Not saying these guys are not being honest, totally possible they got two shots on that HUGE target but they make it sound like this was precision shooting and it was hardly that.
