If you can get that case down tight against the bullet, it "may" help your problem.
The problem seems to be the rim of the extr case catching on the shoulder of the next round up in the mag. SOme have been able to tweek OAL to solve the problem, but it seems to be more the rarety than the norm. I shoot a lot of 200grLSWC in 45acp, but switching to a 200grLTC was only a mold purchase away & they are just as accurate, didn't even have to change my powder charge. If you shoot 230grJHP, then 230grRN are a great practice bullet. If yo ubuy Ranier or Berry's, the 200grTCFP works well as does the Berry's 185grHPRN.
