Hey guys im new to using commercial .223/556 ammo. I finally suckered into an ar, 16in bull barrel match trigger ect. Ive been shooting American eagle 556 to sight in and play a bit these last few weeks. I got around to playing with loads, nosler 64gr bonded with cfe223 25.80 charge cci SRP. My load is spot on, real tight group at 100 yards, and just barely barely craters the primer. You really have to study it to see. 95% of my shooting over the years has been with my own loads, very little commercial. I did alot of .223 for my remington 700, and I load .308 all day for a variety of rifles. My Issue is consistently my load is shooting center with the commercial ammo 556 62gr, but about 12in lower. Is this normal for the hotter 556 or what? Both give me tight groups just a different location on paper. Any input would be greatly appreciated.
