no 410 shotguns cannot safely fire 45LC ammo some 45LC revolvers and rifles can fire 410 shells "It is unsafe to shoot 45 LC in a 410 shotgun. The standard bore diameter of a.410 is 0.410 inches in diameter with constriction down to ~0.375 inches if your gun is choked about full choke. The 45 Colt is 0.451-.454 inches in diameter. The.410 shotgun was never intended to fire the.45LC. The.410 shotguns tend to have tighter chokes which restricts the bore to unsafe conditions (Pressure) for a lead pistol bullet" shooting a 45lc in a 410 would be like squeezing a 0.452 bullet through a .38 hole.it would be like trying to use a 45 bullet in a 38

Hi Ronald, no sir, you cannot safely fire .45lc in a .410 shot gun. Most .410 bore shotguns are not proofed for the pressures generated by the .45 Colt cartridge. Also, the standard bore diameter of a .410 is as expected 0.410 inches in diameter , the 45 Colt is 0.451-.454 inches in diameter. That is significantly larger than the bore of a 410 shotgun.
The combo guns you see that shoot both, like the Taurus Judge, are chambered for the larger .45lc.
Stay safe & have a great day

Hi Ronald and welcome. No Sir. Buds has many incorrect listings for .410 Shotguns that show .410/45LC for many shotguns. For Safety and warranty reasons, do not attempt this and verify any questionable firearm functions with the manufacturer, or ask the community here as you have successfully done. Cheers and stay safe!
