I'd ask proof.ok i got it off! tried using a wheeler barrel vice with oak inserts but it kept spinning. so vised the barrel in my machine vise and that did the trick, at the expense of scratching/gouging the barrel, but i figured there wasn't a huge market for factory barrels anyways... used a wheeler external action wrench and just smacked it a few times with a small sledge and it finally broke free.
next question, torque spec pls for spinning on the new barrel (tikka proof carbon prefit)? apply some anti-seize? other tips? thanks!
I put my PVA on at 75ft lbs for 308 case head per their recommendation.
