It shoots holes in dimes with factory ammo
Not trying to be skeptical, but what factory ammo was being shot? I love the .223 Rem cartridge and have tried every single brand/grade/weight I could ever get my hands on. While some have performed better than others, I have never had one that was consistently hitting dimes at 100 yards or more. And this is in guns that shoot under .5 MOA with handloads.
