Those Winchester slugs are “Foster” style slugs. Soft lead with a hollow base/skirt designed to obturate and fill the bore.
In flight the hollow base stabilizes the slug like the skirt on a badminton birdie.
They won’t harm the bore of any modern shotgun but they will lead the bore heavily. My red dot equipped Stoeger will put them into 3” at 50 yards from standing.
One year our HQ bean counter ordered crap ammo for everything, he must have gotten a sale on Winchester’s 1 oz low recoil Foster slugs. They were actually great and I found guys hoarding them years later until they turned in their shotguns for carbines.
they have been in the police academy inventory for years. they were bought by mistake by someone who just bought slugs without realizing there is a difference.
No one likes them (HA, I wonder why). We have some older 870s that are 2.75" only... so I dont take them as I cadet might try to force one in.
I thought about trying some in the 1301 in the next academy, but I have plenty of modern stuff.
I might see if the director can trade them in.

Sorry if I was clear in my reply earlier. I have the stock choke that came with my Gen3 1301T (7+1 version) and have put over 100 rifled slugs of various flavors through it with no issues. Like a previous poster mentioned, they will lead the barrel quite a bit, so you just have to have some patience when cleaning it. I found a bore snake useless, and also found brass brushes to be of no use, even when I hit the bore with a patch soaked in Hoppes and let it sit for a bit. The Hoppes Tornado brush was the only thing that worked to get the barrel free of lead on both my 590A1 and 1301 after running each shotgun in a class firing over 500 rounds of rifled slugs, 00 buck and 7.5-8 birdshot.
Your shotgun will be just fine with rifled slugs.
"Rifled" slugs do not require rifling in the barrel. They have the cutouts on them to swage down the bore hopefully providing better accuracy. In some guns I'm sure they will shoot very accurately. In some they won't.
Like buckshot, you have to try different slugs in your gun to figure out which ones shoot accurately and to the correct point of aim in your gun.
Those are 3" magnum slugs moving at near maximum velocity you will find in a 12 gauge loading. They will have significant recoil.
The best application for slugs like that is hunting medium to large game at longer distances. They are highly likely to overpenetrate making them a sub-optimal choice for home defense.

I will stick with the current defensive rounds.

Mine is getting closer to done! Got the Magpul SGA installed on a GG&G adapter. Also removed the rail & sights and replaced with an Aridus CROM. The optic is an Aimpoint H1. The light is a Steiner. I have a GG&G front sling attachment but right now I can't remember where I stashed it, but it needs to go on. Eventually I'd like to get a GG&G bolt handle or the slicker/fancier one from Briley, and probably the Briley aluminum bolt release. But for now it's getting close to where I want it.
