I want to shoot slugs from my mossberg 500. Should I completely remove the choke or is there a correct one to use. I have the extra full, modified, and imp. cyl. I

You might consider purchasing a rifled choke tube for your 500 and shoot sabots.

I would use the IC for slugs . It will not shoot saboted slugs ,they need a rifled barrel.

IC , is fine. Just use rifled/Foster type slugs. Lightfield does make a hybrid sabot for smoothbore , its the EXP

if I were you i'd try to find a slug barrel I shot a slug out of my 500 and i ripped the barrel ( i had the mod choke in it ) the barrel ripped about 8 inches from the choke tube down

JohnL it sounds like you had somthing in your barrel , mud ? Lead slugs should not do that . A freind have shot lots of slugs of his full barrel.

there was noting in the barrel first shot after cleaning it that's why mossberg says in there manual not for use with slugs

slugs with a modified choke is what I use and It works just fine. Probably the cheapest way to go.

use a rifled slug with the biggest choke you got... in your case the IC

IC all the way. That is wat their plain slug barrel is, IC with rifle sights. I shot that combo for years in my 500. But, just hooked it up with a new cantilevered rifled barrel w/3x9x40mm scope with lit recticle. SWEET! 100 yards, here I come with confidence and a 1900 FPS Win. Sabot!

Wanna buy a slightly used slug barrel? Only been point at 10 or 12 deer...
