Shotgun question
I am not a shotgunner, though I own several of them. I recently saw an article that suggested that you should not shoot slugs through a full choke barrel.

Is it considered unwise to fire slugs through a fixed, full choke barrel?

Yes, it is considered unwise.

Your accuracy may suck, but it is not going to hurt your shotgun. Most guns shoot rifled slugs best with a modified choke.

Rifled slugs are slightly undersized (a 12 g slug is actually about 13 g), they are hollow, and the rifled grooves on the surface permit the VERY soft lead to swage.

Try this- Mike a slug, and mike the muzzle. Hmm- muzzle is bigger.....

There ARE chokes I would not shoot slugs thru- one is called Extra Full. Usually found near a turkey hunter. The other is the old Mossberg C-Lect Choke. Itty bitty steel fingers that are squeezed in or out by a screw type collet (We used to call them Dial-a-duck). Mossberg advised that the fingers could be damaged by a slug.

I always manage to learn something from C3.

I appreciate the response. Thank You.

I have shot many a slug through an old Winchester single shot that I inherited. When I read the article I went "OH ****". The slugs I shot were not rifled, to my knowledge. If I ever feel I have a need to shoot a slug in the future it will be rifled, and I will mike the bore. As a matter of fact, I will mike the bore now....It measures .69" or 17.52 MM. I don't have a slug in the house to measure. A quick google shows a .12 ga. slug at .730, so certainly, something has to give. Thank goodness for good Winchester steel.

I am kind of ashamed to be a "gun person", of advanced age, who had no idea he was so poorly informed for so long. This is a good reason to participate on a gun forum.

there are some choke tubes that are rifled just for slugs to make them a little more accurate and to increase their effective range some.

I have heard that slugs can't be shot thru full chokes for over 40 years. Hogwash. More slugs have been shot in full choke guns than any other choke most likely more than all other chokes combined. This is for the simple reason that only in the last 40 years have other chokes started to become popular. Until screw-in chokes started being standard on shotguns almost all standard shotguns were full choke. Yes I have seen chokes other than full on shotguns made before I was born but they are quite uncommon. I have never seen(or heard of) any shotgun damaged by slugs or steel shot. Give it a rest. Its a non-issue.

Never shoot a slug through a full choke. Over time, doing so will open the choke, and can actually blow out rim chokes or external adjustable chokes. No matter who you know that does so, it's a terrible idea. The choke is being damaged, even if you can't see the damage, which you usually can't. It certainly is not a non-issue.

Nor, for that matter, were all shotguns full choke before screw in chokes came along. Not by a long shot. Many assumed they were, but modified chokes were extremely common. So were improved cylinder, for that matter. A great many chokes were not marked in any way, and test patterns were the only way of telling.

Nor are slugs very accurate through a full choke. I've seen a lot of tests, and performed a couple, and an improved cylinder gives the best accuracy with a rifled slug. A slug that isn't rifled should only be fired through a rifled shotgun barrel.

But a slug fired through a full choke absolutely will damage the gun by opening the choke, and, rarely, by actually splitting the muzzle. Even if it didn't, a full choke is so usually so inaccurate with slugs that shooting them is pointless.

Not sure of the damage to the barrel but a slug through a full choke can put a strain on the shoulder.
