Here's a question for you guys. Let's say I have a rifle with a 0.330" bore, and a mold that drops at 0.340". If I was to use 338 caliber gas checks and then size the boolit down, should I expect to have any issues?
I have an old M95/30 Steyr Mannlicher that I'm wanting to start reloading and casting for (running low on my stock of milsurp ammo for it), and it's odd bore dimensions are causing me to have to get creative.
