I bought 100 Hornady 58 grain v-max bullet heads yesterday and before I started to make loads up with them I got the micrometer and scales out to do some measuring. What I found surprised me. The bullet heads varied by up to 10 thou in length and by up to .5grains in weight. Is this normal ??? I compared this to the Nosler ballistic tips and they were a lot more consistent, the nosler were within 3 thou of each other in overall length and within .2 of a grain. Am I being over picky ???
