Took my AR-15 out today to shoot at 300 yards.
I don’t reload for this rifle, have only experimented with purchased ammo.
I’ve had many loads shoot great at 100 yards. Stretch out to 300 yards today and the Black Hills ammo shot better than others even though the S.D. Was much higher.
The Lake City 62 green tips had a SD of 6.63 and averaged 3053 FPS and would not group minute of groundhog.
The Black Hills 69 grain had an SD of 24.53 and 2720 FPS. Had multiple groups within 1-1/2” @ 300 yards.
BTW. The rifle is a Colt 6940 with a Krieger 16” SS fluted barrel done by Compass Lake. Shot with an AAC suppressor.
