Dthunter, you’re on a good track, don’t cut your barrel. The twist you have chosen will stabilize a lead bullet around 500 gr or a bit more. You don’t have to shoot that heavy of of course, when you start getting in that neighborhood with a tapered RN flat base bullet at subsonic velocity you might be amazed at the BC that results.
Make an "Extra Webley".
Could you get enough [bleep] out of a 45 case to pop a 500+gr cast
bullet out the muzzle?
That can be a thing with light loaded revolver rounds,
is it less so in higher pressure smaller cartridges?
I suppose the barrel length vs gas production question
would be key.
