they are a cheap and fun gun to have (like 80-100$) but by the time you get the scope mount and scope youll be near to over 200$. the barrel tolerances aint all that but can be pretty accurate. if your gonna get a dedicated hunting rifle just look for a savage model 110-111 in something like 30-06 as a package at one of the big stores like Dicks sporting goods or wallyworld. comes with a budget scope but my buddy killed some nice deer with that set up. ive seen them on sale for under 350$ if you wait for a sale. another option would be to slug out the 870 with a dedicated rifled barrel or just throw some fiber optic sights and use a open or imp, cyl, choke and some federal tru ball slugs (like 4$ a box) for a great 100 yard BIG hole puncher.
what kind of muzzy do you have? you could get a cva muzzy inline for like under 150$ and shoot sabots out to 200 yards maybe something like this
