no
Lacking a slug barrel, improved cylinder works best for slugs.
A rifled slug- yes.
Yes
No risk if it's a modern gun in good condition with a shell of the proper gauge. I wouldn't try in damascus barrels or guns with a "poly choke".
Yes: A Remington 870 shotgun with a modified choke will shoot any commercial shotgun slug.
Yes. Standard chokes should be OK. Extra full chokes, on modern turkey guns, no.
Yes, but, DON'T DO IT!!!!!!!!
Slugs will shoot safely through any choke but Improved cylinder or full cylinder should work.
Never fire a shotgun without a choke tube installed. DANGER, DANGER, DANGER
Poly ChokeYes, set choke to cylinder.Yes, you can use slugs in a poly choke gun i have a mossberg new haven model and i use slugs in it all the time just make shure that you open the choke up to mod. or im cyl or just the most open setting on the poly choke it shouldn't matter the your gun is a jc and mines a mossberg when i shoot slugs in it i use the inmrpved clyinder setting its the most open setting that my gun has just make shure you don't lossen the choke too much or you might shoot of the choke all together (my grandpa did that with his 12 ga. anywayPoly Chokes have a "slug" setting or use Cylinder or Improved Cylinder. They are safe with rifled slugs. Ask Poly Choke Inc. before trying sabots which are meant for rifled barrel anyway and aren't accurate out of a smoothbore. http://www.poly-choke.us/choke.htmSee Related LinksSee the Related Links for "Poly Choke Inc. description" to the bottom for the answer.
Yes, but would be better if you put in an improved cylinder choke.
