[QUOTE="budlight, post: 464656, member: 2939"] I've found R-22 and Imr 7828 worked the best with large rifle mag primers like CCI 250 130's don't have a good BC but they go pretty good with R-22 62 gr. 140 SPBT's 60 gr of R-22 and 150's with 58 gr The 7828 again with the mag primer uses about 1.5 grains more for each respective pill weight. Of course start a couple of grains less on the powder and work up to these amounts. [/QUOTE]
