Slight differences in charge weights will increase the SD of the ammo but it's been proven even triple digit SD numbers have no effect on accuracy. That said, a charge weight difference of .5gr sounds like a lot even in a large case cartridge like the 30-06 with a charge weight of 50.0gr. It would probably be much worse in the 30-30 and the 6.5 Swede with charges of only 37.5gr.New question: At ranges of under 250 yards (as far as I intend to shoot) for non-competitive target (wanting results but not against competition per se) and hunting (ie Minute of Deer) will charge deviations of 0.5grs within the same batch make much of a difference?
That said, I use nothing but H4350 in my 30-06 ammo with a 165/168gr bullet and I can achieve sub 1/2MOA accuracy with that powder. I like a slower powder in the 30-06 than 4895, 4064 or Varget.
