I went to the range today to tweak my win Hester 1885 by miroku. Cause I switched from 55 grain to 45 grain and it started shooting a little loose. Is that weight to lite for the twist rate. I'm not sure of the twist rate I think it's 1 in 9 or 1 in 10. It's a 28" barrel high wall. Does anyone have any suggestions as to what ammo I should try next. I don't hand load yet
