Well, sorted my fired brass by brand, then weight... Worked up some accurate loads, and am now ringing 6" steel at 300+ yards. Shot 2" vertical spread, and 6" horizontal on a gusty day, so, not unhappy at all.

Question.... The brass I used was from a batch that had 2 distinct weights, 2-3 grains apart. All shots from the lighter weight group. If I switch to the heavier weight brass, it would reason to have less volume, therefore something should change with pressure/velocity... I'm in the middle of the charge range, so no safety issues, but what to expect??? more or less velocity??

2nd part, what about another brand of brass, same length, same weight, fired by same gun..? Same velocity??

Thanks,
Mike
