checked bore dia. on my new to me lifter 10 ga. both bores .802. choked left .034, right .030. than i had to shoot it the stock has a slight crack but "one shot wouldn't hurt" so i loaded a 7/8th oz load of 8's with 15 grs 700-x and shot it at a 30 in target and got 94% pattern with it
got to love the 10 . now off to repair shop and i will have it for spring turkey season i hope.
