Yes
because the choke is actually slightly smaller in diameter than the barre, for tightening the grouping of shot shells. A slug will cause major problems.
no slugs should on be shot thru a improved cylinder shotgun. if you shoot thru any other choke it can cause the barrel to split
yes
A rifled slug- yes.
As long as the maker doesn't caution against it. Have it checked out by a gunsmith
no
As long as the owner's manual doesn't prohibit it.
Yes: A Remington 870 shotgun with a modified choke will shoot any commercial shotgun slug.
yes you can shoot rifled slugs through smooth bore barell, or use rifled choke for sabots. the sa08 takes the same choke as mossberg...win, etc.
"Choke" refers to the amount that the barrel is constricted at the muzzle (located at the end of the shotgun barrel). The more constricted the bore opening is, the narrower and denser the pattern of shot which can be thrown. Several degrees of choke are commonly available, including full, improved-modified, modified, improved-cylinder and cylinder bore. Full choke barrels are made for long range shooting because they make the shot pattern denser at greater distances. Improved modified chokes fall between the full choke and the modified choke and are sometimes used in trapshooting. Modified chokes are midway between the full choke and the improved cylinder choke. Improved cylinder and cylinder bore or skeet chokes have little constriction and give the greatest spread (most open pattern) when shot is fired at close range. A slug may be fired through a choke so long as the slug can fit. If the choke is to small at best the choke threads will strip and at worst the barrel will split down the middle killing or maiming you. When in doubt ask the dealer.
Yes, but, DON'T DO IT!!!!!!!!
Never fire a shotgun without a choke tube installed. DANGER, DANGER, DANGER
