The mag large rifle primer has the best ignition,most consistent and themost consistent grouping, from what I am told. The small rifle mag has a tendency to string the up and down some. One of my friends in LI has put together a custom made 700BDL for muzzle loading smokeless that uses a shortened 44 case and large rifle primers and he likes BH for where he is not supposed to use smokeless.
