Serious question about shotgun chokes

[Floyd]

OK, while I do have experience with chokes on my Winchester Model 12, the one thing I've never shot in it is deer slug. That's one of the reasons I purchased my new Remington 870.

But yesterday I made a bone headed mistake by not reading the fine print. I saw the price on a box of Federal rifled hollow point deer slugs, not realizing that the fine print said "For smooth bore only".

Now the question. I have one 26" smooth bore barrel that came with the 780. They provided one factory choke with the long barrel, a modified model. I don't want to risk shooting a slug through a choke I don't understand.

Oh, and the gun manual is very useless on this subject beyond the red letter warning never to shoot the gun without the proper choke or slug barrel.

Would an Improved choke give enough room for the slug to exit the barrel?

I'm thinking of testing one round in the rifled barrel and hope for the best. While I may not get 100% of the range I would have had this been the right round for the barrel, I doubt a lead slug will hurt the thick wall or the rifling. I only bought five rounds, after all. At a dollar a round, that's dirt cheap.

Ideas? Opinions?

You might look into a slug choke. I'm pretty sure those are made. If not, see if you can get an open choke. Or maybe, and let me remind you I have little experience here, you could just shoot it with no choke in?

If you shoot anything while you have no choke tube in at all, you run a serious risk of screwing up the machine threads inside.

that said, improved cyl. is supposed to be the best for it seeing as it has more room.

That's what I was afraid of, hence the disclaimer.

Wikipedia seems to imply that a rifled slug will work perfectly well in a rifled slug barrel (as rifled slugs existed before the slug barrel, the barrel was invented with said slugs in mind), though Wikipedia is not exactly the be-all, end-all of firearms.

I may repost this question at the Remington forum for technical assistance with such quandaries.

All I ask is a total lack of kaBOOM before I'm able to use my new shotgun for something basic, like taking a deer with it.

But worry not. I have plenty of the right kind of ammunition for my 870.

With the rifled slug/rifled barrel thing, the only real problem is that it fouls quicker.

I suspected as much. Thank goodness I only have five rounds of the stuff. How I wish the sabot based slugs designed for this barrel were that cheap.

Get the open choke, it's the best path. If you fire the wrong one, you'll know it.

Immediately.

Just clean it more often.

Sabot-discarding shotgun slugs?

Yup.
Remington, Federal and Hornady have sabot slug rounds for 12 and 20 gauge slugs.

Theoretically, it shouldn't matter whether the barrel's rifled or not. The plastic might just glide right through.

Also; (I think) sabot slugs are a waste of cash. We just buy the Remington sluggers for $2 a box of 5 and they work perfectly find. Of course, we hunt woods and you may not, but we can hit the 100 yard target perfectly fine.
