I'm needing a formula for a Knight Vision,the MK-85 that I used for years was handed down to my son for his first muzzleloader season this year,he drives nails with it at 100 yds. using 100 grs. of pyrodex pellets and 295gr. powerbelt hollow points. I've tried a couple of different things for the Vision with no success,I would greatly appreciate any and all info,thanks in advance.
