I've got a 1322 I customized and tuned by myself. I first got the 14.5" barrel, then ordered the LW barrel as I wasn't satisfied. It's been polished and cleaned up. It's extremely picky with ammo. But feeding it what it likes is well worth it. It's picky in regards to projectile diameter. JSBs are slightly over the diameter it likes, but because they're so soft, they still shoot extremely well. I can actually re-size junk Crosman pellets to have accuracy wayyyy higher than they should. But with junk pellets there are still weight and skirt inconsistencies even if I can sort the diameter issue
