[QUOTE="Mike Matteson, post: 2103922, member: 101791"] Variance of one grain is a lot to me. Your variance in velocity isn't that great being a difference of 1 gr of powder. The other is case volume? Did you measure volume in each case? Unless you are shooting over 500 yds then there maybe a problem. The long range shooter are under .1 of a grain. If I remember correctly the Prometheus Gen 11 is less than that. Somewhere around .04 gr difference or less per charge. [/QUOTE]
