I pattern tested my Suhl SXS sidelock at 40 yds today with 34gm No5 field loads and noticed that the pattern was very patchy with some areas saturated by shot while other areas a duck could have flown through without being hit. Will backboring and longer forcing cones make much difference at the pattern board when using field loads? I didnt want to spend the bucks if the improvement will only be marginal. Also will the reduction in recoil be noticable? Does backboring or lengthening forcing cones reduce the presure at all to maybe save wear and tear on the gun?
