M4 Tactical Load Test ( Effect on Zero)

My last video put forth the idea of loading M4 magazines with a staggered load of armor Piercing (AP) 62 gr. rounds, and 50 gr. hollow points (HP). One of the viewers made a comment about that load effecting the zero, and it was a good observation. I demonstrate in the video that there is an effect on the strike of the round, but not enough to change its effective shot placement out to at least 100 yards.
