I had the same issue with my Rem 1187 20ga. It did not like remingtom ammo go figure. I tried several diffrent brands and found it liked the Hornady SST the best. It was expensive to figure out what it liked but it was worth every penny when I pulled the trigger on a nice 8 pt buck and he went down less than 75 yards from where he was hit. If you don't have confidence in your equipment or your ability to preform with it, don't use it. Master your equipment and you will minimize the heartache of misses of bad hits.
