Mine is a super 16, and I shoot the Hornady leverrevolution 200gr ammo. It works fine..I believe the 180 gr is not a good choice, light bullet for a .35 cal, low sectional density as I understand it. The Rem 200 gr Core Lokt also shot well from this barrell, and I took a sheep or two at fairly close range with it. The Hornady round has been my favorite for feral hogs. None of my hunting is what i would consider long range.
