I'd like to work up a cast load for my M1 Garand.
I have four 30 cal molds:
311413
311410
311466
311291
I'm guessing the 410 is too light. Which of the others would be best? My main criteria for the "best" load would be the one the cycles the rifle reliably with the least wear and tear on me and the Garand. I'm less concerned about accuracy as long as it's decent. Looking at the powders listed in the Lyman book I'd prefer to use IMR-4198 (assuming Unique isn't going to cycle the bolt).
Thanks
