Anyone else rocking a Remington 870 12ga with a fully rifled barrel?

Here's mine!
23in fully rifled 3in 12ga Rem 870. Picked this beaut up at a Colorado rocky mountain gunshop for 399 plus tax in 2021. Looked like it had a couple boxes of ammo through it over it's whole life and I took the trigger assembly out while installing the side saddle and it is a 2003 model.

Leupold RDS (1 moa dot) on the cantilever barrel mount. Had to buy 100 dollar Leupold 34mm Weaver specific rings for it as the mount is weaver only.
Tacstar (Lyman) 6pc bolt on shell holder.
5pc shell stock sock.
Blackhawk basic sling with good ol' Uncle Mikes sling stud QD thingys.
2-3/4 1oz slugs are pretty tolerable in this thing. 3in 1-1/4oz aren't THAT bad to be honest... Especially after shooting a dozen of the 2-3/4 slugs before hand.
So Fiocchi slugs are either junk trash in general or my gun hates them as they were flying all over the place when I shot it last weekend. Winchester 2-3/4 1oz slugs were very good as well as the Remington version. I have 30 rounds left of the Fiocchi slugs so I'll just use them as range fodder.

My 20” 870 barrel has rifle sights, but it’s a smooth bore.

Are the Fiocchi slugs sabot style or Foster slugs? The sabot slugs really perform with those rifles barrels. :thumbup:

Stay safe.
They are Forster style 1oz standard style slugs. The Winchester ones seemed very accurate by comparison. I'll have to get more and test them out.
 
Those are designed for shotgun only places and sabot slugs. With a decent scope and sabot slugs 200+ yard shots on deer are a real possibility.

For what I do I wouldn't want a rifled barrel, they are not versatile enough. They are useless with buckshot or birdshot. I have a 20" smoothbore with rifle sights. It will keep conventional slugs into minute of deer at 100 yards. The cylinder bore throws buckshot and birdshot into wider patterns than I care for.

I also have one of the 21" turkey barrels with just a bead on it that takes all interchangeable choke tubes. With an IC tube I could make hits out to 50 yards and it patterns buckshot much better. Obviously it patterns well with a turkey tube and turkey loads, but with other tubec is versatile enough for most any type of shotgun hunting. That is the barrel that stays on my 870 most of the time.

Nice. Yeah I want a 28in supermag as well... Need to thin the herd a bit though...
I do wish someone made a 3.5in chamber that was around 20in...

Mossberg used to have a 20ish inch barrel in their 835 series. I no longer see it in their online catalog or in their replacement barrels. It used to be in both not long ago.

There is the option of taking an 18.5” 590A1 barrel and reaming the chamber to 3 1/2” and installing chokes. If you then back bored it to 10 ga diameter it would be just like an 835 barrel and would fit on 835s.

These days there isn’t much real call for 3 1/2” 12 ga shotgun chambers….if there ever was. 3” will work for 98% of what shotguns are used for.

Yeah I just have a small stockpile of 3.5in goose shells. So that's why, but a 28in would be best for those loads... I have a 5.56 10.5 SBR for close quarters lol.
 
In Illinois, until this year, shotguns, pistols, and muzzle loaders were all that were legal for firearm deer season. Several years ago I bought a 12 gauge Mossberg rifled barrel with scope mount designed for the Remington 870.
It basically turned my 870 into a rifle, just a little heavier. Both deer I have shot with it dropped in their tracks using the Remington sabot slugs. I do, however, look forward to using my .44 magnum rifle this season.

Have you shot the Winchester Deer Season slugs? I saw some on one of our wholesaler accounts and they look pretty nice. 1-1/8oz at 1600fps.

A 1 1/8 oz slug at 1600fps is a bit hotter than the Winchester 1 oz foster slugs @ 1600fps but only a little. Looks like they are designed after the Brenneke….which isn’t a bad thing. I will be on the lookout for some of them. Not often you see new full bore slugs coming out.
 
I have one but the barrel is actually from Mossberg (aftermarket). I put a Nikon 2-7x 200 BDC on it. I have taken a couple of deer with the 300 gr Federal TC sabots but it shoots the Hornady 300 gr SSTs better.

Nice! How do you like having a scope vs a red dot? I figure at 70ish yards I'd be fine as the 1moa dot covers a typical medium size paper target at that distance... For longer range I have other options like my 6.5 PRC.

I didn't even think about a red dot when I bought the cantilever barrel. I'm so used to scopes. I haven't shot it over fifty yards but being able to put three different brand slugs in an inch and a half at fifty yards gives me confidence in the scope.
 
Tolerances in shotguns aren't as tight as rifles. Vibration and movement of the barrel in the receiver can affect accuracy. Pinning helps to reduce this according to people that know more than me. But by doing it you eliminate the ability to swap barrels unless you take the pin out.
