Just bought a new 300 WSM. Have loaded for a few in the past and had good luck with RL 19 and 180 gr Barnes bullet. Made bullets through whole range of recommended charges from Barnes manual. Bolt of rifle jammed on evey se from 63 gr - 69 gr. Does rifle just not like this powder? How can I bring down pressure? Will seating the bullet deeper help me? Recommendations please.
