[QUOTE="lancetkenyon, post: 2844253, member: 68875"] Even different lots of factory ammo can vary greatly. 7PRC has 3 different powders with the same ammo. With 120fps difference, amd different POI for each with the same rifle. That makes a ballistic turret pretty much useless for anything over 300-400. Handloads can vary too, depending on powder lots. I have found some big variations in lots. RL33 has upwards of 140fps with the same charge weights in one lot to the other. I have a slow lot of H1000 that is 50fps slower. I have an 8# of H4350 that is 40fps slower than others. Let.alone the effects of altitude and temps. [/QUOTE]
