as long as it aint broke it should work. i regularly hunt with a winchest model 50. made sometime in the 50's or early 60's...has a plain barrel and mod choked barrel..i love that gun and shoot it amazingly well. dove, grouse, squirrels, bunnys pheasants, woodcock and even a fall turkey died death due to me and that gun. the fall turkey was at an amazing distance. i had no idea it was as far as it was but it was well over 30yds. 1 shot rolled it too. ive fired 100s of rounds from it in the dove field..funtions great..i love it.
