I have owned a 12 GA 940A for 35 years, and it WAS in pristeen shape. Just this year I shot a coupple slugs through it. I will never do that again! The barrel was slightly scored, and it opened at the break point, each time! I did minor dammage to the gun, and Im lucky I didnt get hurt.
of course you can
The Stevens 59A can shoot all size loads from #12 to slug. So in short, yes.
Yes. Be careful if it is choked full.
yes you can but onaly riffled slugs
The last one I saw today had a 28 inch full choke barrel. Sure I would shoot buckshot out of that shotgun all day. I don't know about slugs though. The box of slugs state that they will shoot out of any choke; however, IC produces the best results.
yes
Yes
It is not recommended to shoot slugs with a power pack chock on a JC Higgins model.
Most shot guns can handle deer slugs.
if it has a choke like poly and or screw in choke dont shoot slugs as it can dammage it
yes it can shoot slugs
Yes it will shoot slugs and buckshot, some use them as a deer gun.
