I bought a couple of Lee 6 bangers (200 grain RNFP plain base and 240 grain gas checked SWC) with the intention to cast up a bunch of boolits for my Marlin in 44 mag. I have not slugged the bore. However, a .430 12 BHN boolit from Missouri Bullet shot well over 6.7 grains of Trail Boss and a commercial cowboy load shoots very well. I plan to measure a bullet from the commercial cowboy load as an additional bit of data. Assume I need to pull it from the case to get a real measurement?
The plain base boolit will be for a low recoil load, probably over Trail Boss or HP38. I will cast with range lead plus some pewter for a softer alloy. Once I figure out what diameter the mold casts, I will know what I have to work with and will either size to .43X and experiment or simply shoot unsized and see how it goes. The gas checked boolit is where I am a little less clear on how to proceed. I will cast it from COWWs plus some pewter for a harder boolit with more antimony. I will be shooting for 3% antimony and 3% tin. I would love to have the option of shooting them unsized, but do gas checks require sizing in order to stay on? I know I can slip them on the bases, but do they have to be crimped via a sizing die?
