Hi, Ive been lurking here in the UK for a while but now getting stuck in....I have a marlin 1894c which I reload for successfully ( 158gn jacketed FP ) but have recently got into the dark art of casting my own using range scrap. My problem is this, I have a small stock now of various bullets and await a .357 sizing die ordered some weeks ago. Having read and learned I duly slugged my barrel...results; .357 throat, .355 to the muzzle. Will this sizing die be suitable for my bore (18.5" microgroove) or should I go for the .358 die?
PS I also have an RCBS 35-200-fn gas check mould coming my way, do I have to gas check these or can I load as is?Opinions welcomed, Moorman.
