I tried to get at this in another sub forum without much luck, so I'LL try here. I want a 330-350 gr bullet to shoot in my inlines and caplocks. I slugged a couple Knights and came up with .460(widest measurements from bottom of grease grooves) I don't have the tools or brain power to actually measure depth of grooves. Thinking true bore size is probably near .451 or .452. I have some cast Gould's that mic @ .460 but way too big to seat easily with ramrod. Not sure if I need custom mold or get a Gould and run them through a sizer. Any help you can provide is greatly appreciated.( I do want to shoot this bullet as a full bore lubed bullet, but also size it down to .446 to paperpatch)
