I am running MBC Bullseye #1 200 SWC, coal 1.225, .003" of crimp, 5 gr 231, mixed range brass and a cci 300 primer.
What is happening is I get one jam in about 15-20 shots. The Kimber is several years old and has about 500 rounds through it. I am wondering if this is a spring issue rather than a loading issue? Maybe the mixed range brass can be problematic?
