Thanks for the replies. Sounds like pretty much anything goes with non-magnum calibres provided not pushing the limits of energy/distance. Think I would go .308 due to versatility and ammo availability. Just for the record, I'm happy with my little 300BLK bush outfit. It's pretty much perfect now that I have given up on the subsonic project. The only issue is ammo availability. Hopefully, that will resolve itself!
