Irish you made a good decision. I have the same gun but I have a blued barrel. I shoot 150 grains and a 250 grain barnes bullet. I shot a clover leaf group at 90 yards with this load off of sand bags. I do not like the recoil of this load though. It is fine off of a bench or on the ground but in a tree it really rocks me. I am going to shoot 100 grains next year and the same bullet to get rid of the recoil. I have shot at 4 deer with this load and only killed two. One that I missed was only 20 yards ( yes it was only 20 yards) very bad mistake I still don't know what happened. Yes I do operator error. Oh well I clean the bolt and breech area after each shooting session. It isn't that hard to clean it at all.
