I shoot the Rem factory 150 Core-lock in mine. I know not very exciting but they shoot under 1" at 100 and they are $15.88 at Wally world. I started with them to break the gun in and accumulate some brass they shot so good I never changed. I have tried some handloads but nothing has shot any better. I may have a load worked out with a Hornady SST and Varget though.
