1320yd shot

[LRRPF52]

Hey LRRPF52 as the cats out the bag Sureshot and I will be back at Sandy I think November and hope to have the 6.5 x 47 AR10 there for all to see

That was the chambering I was really looking into when having GA Precision do my last AR10, but I went with .260 Remington because of brass availability. I do like the performance of the 6.5x47 Lapua, and my Finnish cousins did their homework when they put that cartridge together. I like it because it uses a small rifle primer, and has good case design for efficient burning, and you're bound to have a very good case fill no matter what bullet you're loading.

My Irish partner has an RPA 6.5x47 Lapua that he pushed hard, running 140gr Bergers at 3000fps from a 25" barrel. You would have to yank the trigger if you could with that rifle to miss. He put down 900m targets at FinnSniper like it was easy or something (former Royal Marine Sniper).

As to transonic flight characteristics, I have shot a lot of .338 LM at extreme distances, and have observed some interesting things on aluminum silhouette targets. At one long range event, at about sea level in Finland, I noticed that some .338 LM projectiles had plowed through the targets in a keyhole shape, but at consistent orientation nose-up and at an angle. What appeared to be going on was the rotational spin of the bullets kept them oriented to the bore, so that when they passed over the maximum ordinate, they didn't nose over like a spear, but came in like the Space Shuttle with a high angle of attack, but still plenty supersonic.

I then considered the terminal ballistics implications if one were to be unfortunate as to find oneself in the crosshairs of a shooter equipped with such a weapon, especially these guys who were making reliable and consistent hits on man-size sils past 1100 meters. It would be ugly, to get hit with a 250gr pill like that plowing down at you in the highly arced path of the bullet's final milli-moments.
