I have the same rifle and caliber as you but without any custom work and have been real pleased with mine. I' ve had mine since aprox 1991. I normally hunt with Winchester Supremes in 150 grain and have had excellent results with this bullet. I don' t shoot it to often so I just stick with what' s working. This gun has never let me down. I wouldn' t mind getting a trigger job on it, but when I shoot it as well as I do it' s just not on the top of my list of things to do yet.
