Just purchased a 1980s production marlin 782. Gorgeous gun in gorgeous condition but for one little issue. When feeding ammunition out of the magazine the ammo is pushed up at an angle where it misses the chamber and stove pipes (standing tip Straight up with rim down [12 o clock]). if the bolt is pushed forward further crimps the brass on the side. Does anyone have any idea as to why the rounds are tilting like this? Can post pictures if needed but I figure this may have been experienced before.
