Get a RBL with 30 or 32 inch barrels. I installed some Carlson Imp Mod and light Mod sporting clay chokes and it patterns great. It especially likes 3" Federal 1 3/8 oz of #3's steel. It patterns awsome even at 60 yds,but the pellets may not have the energy to kill at that distance. It's a modern gun designed for the magnums so there will be no issues to deal with.
