I had a different post on here about it. Ive tryed everything to get it right and it just dosnt shoot well. its a Rossi Single shot i got for $100 new just to have in the truck for when im up to mountains. Ive tryed every different type of ammo i could get. I have around 16 half boxes laying around and i know i shot up atleast 10 other full boxes. The best group ive ever got is the first 2 shots out of a cold barrel they will be around 1 in but they are anywhere in the 15in circle.
