... I've seen RL-15 vary as much as two grains in cases the size of the 9.3x62.
I have two lots of RL15 noticeably different in density. With my Redding BR-30 set to throw 42 grains of the light lot, it throws 43.6 grains of the heavy one. Interestingly those two charge/lot combinations shoot about the same under a 168 in my 308 rifles.
