[QUOTE="brentc, post: 1291714, member: 16938"] Another thing to consider is the difference between virgin brass and fire formed. If you saw 2840 in virgin brass, there is a chance you could see an additional 40-50 fps increase and a tighter ES in fire formed brass with the same load. Powder capacity increases when the case is blown out to chamber specs. This is especially true in belted mags headspacing off the belt on the first firing. [/QUOTE]
