.45LC/410 question

Commygun · July 9, 2001, 06:39 PM

I have seen a few guns capable of firing both .45LC and .410
shotgun shells. That raises a couple of questions. If the barrels
are rifled for the .45 won't that result in errant patterns with
the shotshells? Would the rifling be damaged by steel shot?
Is it safe to fire a .45LC from a smoothbore .410? Of course
accuracy would be poor (maybe nonexistent) but would it be
safe? How does the .45LC compare to the .410 slug in terms
of accuracy/power/lethalness? Any insights would be appreciated.

A few words of advice....

Don't do it!!

Like any compromise gun, it's not as good as a firearm used with one type load.

As for using one in the other, life is too short for this. Stick to what is supposed to go in the gun...

My guess, firing a 45 LC in a 410 may or may not split the case, or cause a gas blowback, but accuracy will not be there.

And, in the case of some of the hotter loads suitable for the Rugers,etc, you might just blow your 410 and yourself into the next incarnation.

I know H&R makes such a shoulder arm. I *believe* it has a screw-in rifled choke for stabilization of the .45 Colt rounds...

I think the most practical firearm that can fire either round is the handguns, such as the derringers chambered in .410/45LC. One problem you can run into with firing a 45LC from a .410 that was not designed to fire 45LC is that the bore is made for a .41"" projectile. The OD of a .410 shell may be close to the OD of a 45LC shell, but the plastic is thicker than the brass. You can easily get your slug stuck in a long barrel and have an uncomfortable increase in pressure.
