I have the following, Winchester trapper with a 16" barrel with 1-38 twist, accuracy with target load is terrible. Same load in a contender 10" with 1-20 twist shoots great. Also have a 24" Encore 445 with 1-16 and like it so far. Accurate, but not a gun i enjoy shooting for long periods, that seems to like the hot suff. Still working on an accurate target load.
