I also have a PSA 12, mine is stainless. Before ordering, I read several times that PSA has a 1.5 MOA guarantee? Im sure someone here can confirm or debunk that.
Something Ive had good luck with is JB Bore Paste. It is an abrasive, so use sparingly, but Ive been using it to speed up break in on rack grade barrels with great success. If you have any burrs on the crown, or rough places in the throat, a little polishing can make a huge difference. Im shooting right at MOA with my pistol with 50ish rounds down the tube using Hornady Black. Im using a JP Enterprises trigger because thats what was in the lower I had.
Im glad to hear that more well used barrels are shooting SSTs better, as I have 100 rounds of it I had decided may have to go into the plinking ammo pile. I havent tried it yet, but Ive yet to read about anyone raving about how accurate it is in their barrels.
