I purchased a Mossberg 535 this past March mainly for turkey hunting. my question is can i use it for deer hunting without having to buy a rifled barrel? I dont have the money for that and my shot wouldnt be more then 75yrds. The salesman at Dick's where i bought it said all i would need is a rifled choke and i talked to another one and he said i wouldnt need anything just a rifled slug. I am really confused and dont know what i need so any help is appreciated. also it came with two barrels 28" and 22" and it has Modified, turkey, full, and imp cyl choke.
