After trying 10 rnds at my pet load of 25.1gr, I loaded 10 each at 23.0, 23.5, 24.0, and 24.5, I couldn't get a group under 5 moa... at that point I reconfirmed my 25.1 with 55g SGKs I had = or < 1 moa. Ive found those game kings are great little bullets. this was all at 100yds. This left me with 450 out of the 500 which I loaded over 23.0gr of CFE 223 for "shoot house" ammo. Ive got about 300 rounds left. I did also try it in three other AR's I have, another BCM, a Spikes Elite, and a Black Hole 16" carbine length P3 (incredibly accurate barrel). I really thought it was something I did but the sub par results are consistent in all my rifles. All of these rifles have been proven to shoot sub MOA on the sled with a good load.
