Thread: 577-450 case forming

I've never used filler in my martini cases and occasionally load down to 60 grains, that's the max I can get in the SPANZ brass. The Bertram will hold a full 85 so there's a bit of air space with 60 but it isn't a problem. I also don't muck around with card and grease cookies or paper patching just a simple lee 405 or 500 cast bullet lubed with lard and beeswax. Not traditional but cheap and cheerful and it works
