I want to build a bolt action rifle for my kids that will shoot a commercial 90gr .314 SWC or similar cast boolit subsonic from the widely available (usually) .308 case. It would be nice to shoot a 123gr to 150gr (.312) full power load once they are ready to hunt. What is my ideal barrel twist and length. I would like to keep the barrel under 18" but am open to suggestions. Is this a stoopid boolit idea? I'm humble. Tks ahead.
Will probably be a Remington seven or 700 action with a red dot.
