I’ve loaded tons of 45 auto, 308, 270 and some 300 WM as a reference.
So I’m loading 44 mag and 10mm for the first time. Rockchucker single stage. Carbide dies. 44’s going off without a hitch.
10mm’s in loading RMR 180 FMJ-FP’s. I was getting some buckling on some of the last rounds out of 100. My expanding/flaring is very conservative (ie. just barely belled). Like so much so that I have to hold the bullet above the case on some rounds. The bullets all drop in the barrel with zero interference.
I was gonna try a little deeper with the expanding plug. But I wanted to try seating all the bullets, then backing the seater out and doing the crimp in a separate step. I have no idea of the quality of the RCBS die’s taper crimp ability vs Lee FCD or Redding dedicated dies. I figured that a separate crimp process is a 4th step anyway.
P.S. The brass is inconsistent. Some of it is as much as .010+ shorter than trim-to length. Some of the cases have a slant when looking at them side-on. I’d trim them, but again, those cases are already too short.
I’ll get all Starline here eventually. It’s range brass. Some good ones, but there’s many pieces of hot trash in there that I’m gonna have to toss.
Opinions? Education?
