don't have an answer got you per se, but I've purchased a barrel from McGowen. They are really friendly and helpful over the phone. I would give them a call on monday if I were you and you'll have your answer that fast. Their barrels are awesome! I am still fire forming 270 Gibbs from std Win. Brass and cheap 130 gr Rem bullets over W760 just because I had a lot of it laying around. I am getting .5 - .7 inch groups already. Very impressed with their barrel.
