I took shots out to 600 on various steel targets. 200 was 2.3 MOA, 300 yards was 5 MOA, 400 yards was 9.1 MOA up, 500 13.4 MOA, finally 600 was 17 MOA. It was so much fun, I shot pig silhouettes, rounds that were from 9 inches at 300,to 16 inches at 400.You like it at 600 yards, you'll love it at 1000. Your holdover will be about 38 MOA, and your energy with a 123 gr will be around 430 ft-lb, (~1256 fps). About what a .40 cal pistol has at the muzzle, or thereabouts, with 155 grain. I've got to try some of the ELD's; I still have about 400 hundred 123 AMAX left, and maybe 150 SMK 123's. I like the SMK's a lot, except they're more expensive. I get about 2" less drop at 1000 yards with them than the AMAX, with the same powder load. I'm using AA brass, 31.5 gr CFE-223 and WSR primers. I get 2640 fps MV (20" barrel 1:8 twist). Generally, I can get 7-8/10 hits on a 18x18" plate at 1000 yards, and have hit as far as 1125.
It is amazing out to 600 yards, the power that the Grendel imparts to a silhouette. It just smacks it, and to watch the target hit dead center and shudder. Nothing like it.
