C.N. Double Posted February 3 Share Posted February 3 What cast loads are working well for y'all? I have H/IMR4198, Unique, Clean Shot, and WST on hand, but I'm not opposed to getting something else (if it's relatively available). Gas checks or not? Bullet diameter/weight? I have some of Norm Purcella's 150gn GCFP (.309) and 170gn GCSil (.310), but I think they might be a wee bit heavy. I'm also reading that the round nose is important for proper feeding. I can get some 120gn .309 RN bullets from Bear Creek pretty easily as well, but they aren't gas-checked. Primers? I have a handful of Fed Mag SPP, but I know the M1 Garand can sometimes set off the softer primers when it cycles -- does the M1C have the same issue? I'd guess not since there is so much less mass in the bolt group. I know .30 Carbine uses SRP, but the Fed Mag SPPs are the same. Tell me about the crimp -- firm crimp or not? Thanks for your help!
