[QUOTE="J E Custom, post: 543706, member: 2736"] I find that non magnum primers work very well in all but the very largest cartriges. In cases with a powder capacity of less than 90 grains I actually have lower SDs than with magnum primers. The velocity is slightly higher with the mag primers but not much and the lower SDs of the non magnum primers makes it more attractive to me. Also the powders you mentioned are not that hard to light in cold weather. With the very slowest powders, magnum primers are sometimes needed when case capacity exceeds 100 grains.
