I have a Rem 700 SA 308, I’d like to re barrel it into a 16” tube shooting a heavy subsonic. This would mainly be for entertainment purposes, night hunting pigs under 100yards, etc. I know the Beowulf is a 223 bolt face and short action, what options do I have in the 308 bolt face? looking for an out of the box solution. I do reload and I’m not scared to do something outside the norm.
