Yes, I know the Pacific RL350 is a relic from the past but I have one in good shape. I was using a Pacific/Hornady 105 single stage and it produced perfect reloads every time. Got the RL350 for free and like the progressive for speed. The problem is the crimp. Sometimes it doesn't close fully, sometimes it closes with just a small hole in the center (OK by me) and sometimes it crimps correctly. I keep the old 105 to use as a final crimp station on the ones that don't crimp correctly as it always finishes them perfectly. Works but just another step. The bad crimps occur randomly, about 20 out of 100. I noticed the crimp die in the 350 is spring loaded while the 105 is solid. Any advise on adjustment would be appreciated. The load is: Gun Club hull, 15.0 E3, ClayBuster 1118 wad, 1 1/8 oz of #7 1/2 or 8.
