Okay so I just picked up a new Marlin 336 and was planning on shooting cast only out of it I haven't had a chance to slug the bore yet or even fire it for that matter the action had some binding issues and is in for warranty work.
My question is what is a good mold in the 140 to 160 range would prefer a round nose but am not opposed to flat nose either. I'm sure that its gonna want .310-.311 sized boolits but the only molds I can seem to find are listed as .309 so does anyone have any advice do these molds drop larger diameter than listed or am I just being too picky.
Thanks
Jr.
