Factory ammo is the wild card, but I'd expect three shot groups in the 1 1/2" to 2" range. With handloads you ought to be able to get at or under moa.
After market barrels aren't a guranteed way to get top accuracy. I had bullberry make me a 218 mashburn and I've never had to work so hard to get a barrel to shoot moa. But when I finally found the load it liked, I could shoot a box of ammo at the permanently installed 150yd turkey sillouette's head and never miss.
