So was at the range with my hand loads. Had a weird issue happen twice. Gun fed a round into the chamber, but it only went part way. Couldn't pull the charging handle to extract it either. Had to hit the charging handle with a rubber mallet to get the round out. Im wondering if my seating die was pressing the shoulder out some? Its supposed to have a crimp built into the seating die (RBCS). The COAL was fine as I fired 18 other hand load rounds no issues.
