Make sure to run a tight patch through the bore to see if you notice any washboarding. Some of the TC .45 barrels, in particular some of the 1:20 twist stainless barrels, had such problems - and wouldn't shoot worth spit. I got lucky in that the first Encore I ever bought had such a barrel. It was replaced with a 1:28 twist barrel that was MUCH better.
Many blamed the 1:20 twist for the inaccuracy of those barrels. I didn't. 1:20 twist .45 caliber barrels will shoot great IF they are good barrels.
