smallest bullets i shoot out of my wolf is a 445gr conical, largest being 590gr gas checked bullet i cast. no issues and suprisingly accurate with these large bullets. the felt recoil with this gun is a bit more than with any other ML i have tho, but its fun to shoot and easy to clean as well. i chronied some loads last week with a different rifle, it has a 22" barrel as opposed to the 24" on the wolf, but let me say that even at 125gr of pyrodex P behind the 445gr bullet only went about 1450ish. for a large bullet like that, its moving pretty good still, but i dont shoot big bullets for the speed... ;Dnext
