Tikka barrel removal today was my roughest yet. Older T3 in .243 that was barely shot. After letting the penetrating oil do it's thing for a couple days, I proceeded as I usually do. Tightened down evenly in my SAC vise with drywall tape around barrel and used an external wheeler wrench with a cheater bar on the action. Initially the barrel spun on maybe the 10 whack with my hammer. I was able to tighten the vise a touch more using the cheater bar and ratchet and that did the trick. Barrel has marks from spinning, but otherwise no major damage.
