Absolutely not. A .45 Long Colt bullet is nominally .455 inches in diameter. A .410 is .41 caliber. The cartridge will fit because of the extra chamber diameter to accommodate the thick body of the shotgun shell, but attempting to fire a revolver cartridge will result in overpressure, a burst barrel, and likely injury.
The chamber pressure of a .45 LC is higher than a shotgun is designed to tolerate, to begin with.
A shotgun can shoot up to 80 yards it it depends on what the choke is on the gun.
Depends on the load and what the maker of the choke/shotgun say.
Slugs will shoot safely through any choke but Improved cylinder or full cylinder should work.
Yes. Rifled slugs are intended for smoothbore barrels (abot slugs aer for RIFLED barrels). Best accuracy with rifled slugs is USUALLY a modified choke, but can be safely fired thru any choke less than EXTRA full choke.
Yes, but, DON'T DO IT!!!!!!!!
Pellets or slugs. shotguns usually shoot shot or pellets, but you can shoot slugs. in Indiana we use a shotgun to hunt deer and use shotgun slugs, better to use a barrel with no choke in it. cylinder bore preferred.
Cylinder to Full depending on what discipline you are into.
yes for a shotgun you need a rifle barrel DO NOT shoot slugs if you have a poly-choke!
Never fire a shotgun without a choke tube installed. DANGER, DANGER, DANGER
Yes.
Depends on how old the shotgun is.
Yes: A Remington 870 shotgun with a modified choke will shoot any commercial shotgun slug.
