View Full Version : Mossberg 835 and Slugs
April 8, 2011, 12:21 PM
I recently bought a Mossberg 835. I live in Greece and here we are allowed to have only smooth bores.
My questions is if I can shoot slugs from this shotgun. I know that is overbored and the accuracy will not be very good. But can I or wiil damage the barell?
Thanks for any answers/suggestions.

No, you won't damage the barrel. But yes, accuracy will likely be poor. Most slugs are capable of being safely fired from a full choked "standard" bored barrel, much less a choked barrel in the overbored 835.
Try a Brenneke type slug. They usually work well in smoothbores.

I am willing to bet your 835 came with screw-in chokes. I am also willing to bet, you can find a choke that will optimize a give slug's performance from that over-bored barrel better than you may think.
You want to choose the "Improved Cylinder" choke tube. Here is a link to O.F. Mossberg for your edification:
Let us know how this works out for you.

I really appreciate your answers.
At the moment I have an ULTI FULL Turkey Choke Tube that came with the shotgun.
I think Improved cylinder is too "open" for slugs. Should I try something tighter?
PS. My bore diameter is .775''

Read the Mossberg site's fine print in the choke tube section for slugs, they suggest you use the improved cylinder. I can tell you now do not use the full turkey choke. Better yet, email their customer service and ask them directly about choke tube selection,

Ohhh.. I dont even think about using the turkey tube for slugs.
I am planning to buy an other one for that use.
I just ask if my overbored barell can shoot slugs without problems (except accuracy).
Thanks for your help

I am just wondering...
Is there anyone that shoots slugs with a mossberg 835 smooth bore or it is just me?
April 8, 2011, 05:05 PM
Don't do it if you have a standard shot barrel. I have an 835 made in the second year of production and the barrel is marked "Do not use slugs". Because of the overbored barrels (bored to about 10 gauge) a slug could go sideways early in the barrel and cause problems. Buy a smooth bore slug barrel for it; the Mossberg part number is 90800 for the smoothbore cylider choke slug barrel.
You don't have to believe me, just email Mossberg and ask them!

SHR970 is right. DO NOT USE SLUGS IN AN 835 with a standard overbore barrel. You have to get a special slug barrel for it.
April 8, 2011, 08:42 PM
As stated in the owners manual "835® Models are designated to fire 12 gauge 2-3/4”, 3”, or 3-1/2” factory loaded ammunition.
Do not fire slugs of any type (single projectile ammunition) through the overbored 835
Accu-Mag barrel. This barrel is designated to shoot lead or steel pellet shot loads only. Use
only 835 barrels designated specifically for slug shooting"
SAFE SHOOTING Bill

Please do not shoot slugs through your overbored Mossberg 835 barrel.
Your barrel likely says on the side "Not for Use with Slugs". As some posters in this thread have already indicated, the standard Mossberg vent rib AccuMag choked barrels are overbored to 10 gauge dimensions. 12 gauge slugs can wobble sideways in the barrel and hang up causing an obstructed bore and potentially a kaboom.
There are slug barrels made for them.
To the other posters in this thread advising that it's OK, please do some reading on Mossberg's website about the 835 and it's specs.

Thanks guys. I really appreciate your answers.
I will ask my local gun store in they can import a smooth bore slug barell.
Wish I could own a rifled one but my countries laws do not accept rifled barells.

I am trying to find a smooth bore slug barrel in woodland camo.
Anyone seen one before?
April 9, 2011, 02:56 PM
They exist, but I haven't seen one new in quite a while. I think they have been discontinued and the used market may be your only option. Difficult given the import/export need.
April 12, 2011, 08:03 AM
I contacted Mossberg and they told me that the only smooth barrel for model 835 in woodland camo is item# 12327WD BBL ASM 835 24RBRS WDLND PORTED.
But the Mossberg distributor in Greece told me that they cannot order it.

I also have a 835 but it doesn't have an overbored barrel. It should be fine to shoot Rifled slugs out of the gun.. I would use improved cylinder choke to fire it. Bought some magnum 3" they should kick pretty hard!!!:D
April 12, 2011, 01:26 PM
Mine is overbored and on the side says "NOT FOR USE WITH SLUGS"

Is the barrel vent ribbed with removable chokes? If so, then very likely you do have an overbored barrel (they come that way from the factory on the 835). If you have a plain barrel with bead only, or a smoothbore or rifled slug barrel with rifle sights, then it's not overbored. Actually, I'm not so certain that the plain 18.5" cyl/bead barrel isn't either. Never held one of those specimens first hand.
The 535 on the other hand is a 3.5" chambered 500 basically and is not overbored from the factory.

The fact is you have a 10 gauge gun with a extra full 12 gauge choke and its good for goose and turkey not deer. As much as I like shooting slugs I would not shoot them out of that gun. Re-barreling will get you the same conundrum. You might want to think seriously about looking for another Mossberg in the 500 model class and fit it with an IM choke and a 2X power scope. You are good to go out to 100 meters if you need to shoot that far with standard Foster or Brenneke slugs with fair accuracy and no worries about damaging the barrel.

Thanks for your advice.

I decided to follow Old Grump's advice and buy a Mossberg 500.
What choke to order for slugs? Skeet or IC ?
April 14, 2011, 09:38 AM
Either will work. This is from memory but Briley chokes go Cyl, Skeet 1, Imp. Cyl., Skeet 2, Mod.
Now I understand you can not have rifled barrels, but are you prohibited for using rifled choke tubes? If you are not prohibited, I would recommend one of them because yuo can then add the various sabot slugs to you ammunition choices where available.

Rifled choke tubes in Greece are illegal...

I typically use IC for slugs or a fixed choke IC barrel. That's with Remington guns. Mossberg for some reason doesn't choke their slug barrels and leaves them Cyl bore. Maybe try a Cyl accuchoke? Or can you get a smoothbore 500 slug barrel there? or a combo gun that comes with both barrels?
Having the dedicated slug barrel also gets you the rifled sights to better use the slugs. Here in the states there are guns with 2 barrel combination sets sold.
April 14, 2011, 01:02 PM
I can get the 500 smooth slug barrel here. I ve seen it and i liked the sights a lot.
I will start with the field barrel and maybe I will buy the slug barrel later
April 14, 2011, 04:20 PM
I have one with the slug barrel, one with the IC choke and one with the IM choke. They all work good enough but I get groups just a bit tighter with the IM. Only choke not to use no matter what is the extra full and cylinder bore. The first is bad for the gun and the second is bad for accuracy.
I have the fiber optic hi viz sights on the slug barrel and on my semi auto smoothbore, Mossberg M9200 and I just love them for fast shooting.
