One holer per shot maybe! I never new the 760's or 7600's to be more accurate than a bolt action and there arn't too many of those in a factory gun that will shoot one hole at a 100 yards for 5 shots. Any factory gun shooting under an inch at a 100 yards is very good. If you get that 760 shooting in the 1.5" range I would consider it a good shooter. Did you clean the copper fouling out? If you use something amonia based like sweets, run patches through it until you don't see blue. Let em sit for 10 minutes or so between patches. That will help accuracy but it will take a long time to get it clean i'm guessing. Good luck
