Shotgun slug question

[aclawrence]

Hey guys, I’ve got some brennenke slugs that say for rifled barrels on the box. I’m trying to figure out if I can shoot them through a modified choke. It’s the most open choke I have. Anyone have any thoughts on this?

Well I think it’s a no go with these super sabot slugs and my barrel so y’all can ignore this.

they will shoot and not hurt the barrel. however accuracy may be out the window.

if you keep the range short enough they will kill about anything.

You could probably find a rifled choke tube for a smoothbore. I used to shoot a 12 ga. with a rifled choke tube. Shot the Winchester BRI's just fine. I made the switch to 20 ga sabots with fully rifled barrels and never looked back.

Rifled slugs= smooth bore barrels
Sabot slugs= rifled barrel, or at least rifled choke

I’ve decided not to shot the slugs but I think I will start looking for a rifled barrel. We have a hog season in March that I can use a shotgun during. Thanks for the replies. An old box of slugs is going to cost me some money haha

Exactly

It is not safe to shoot slugs through a modified choke. Use a cylinder choke for rifled slugs or a rifled choke for sabot slugs.

I would like to see that in writing by a manufacturer.

I found many comments like the below.

from wiki

Design considerations[edit]
The mass of a shotgun slug is kept within SAAMI pressure limits for shot loads in any given shotgun shell load design. Slugs are designed to pass safely through any choke, though accuracy may suffer. The internal pressure of the shotshell load will actually be slightly higher than the equivalent mass slug projectile load, due to an increased resistance that occurs from a phenomenon known as shot setback. Common 12 gauge slug masses are 7⁄8 oz, 1 oz, and 11⁄8 oz, the same as common birdshot payloads.

Copied right off Benelli web site:

Which chokes are recommended for slugs?
These chokes are recommended for slugs:
4 notches = Improved cylinder
5 notches = Cylinder

A cylinder choke is recommended for shooting rifled slugs in a smooth-bore barrel. Sabot slugs should only be shot through our fully-rifled slug barrels.

It is not safe to shoot slugs through chokes tighter than those listed here.

Copied right off Weatherby web site:

The Use of Slugs
Smooth bore barrels with choke tubes should have "Cylinder Choke" tubes installed when using Foster or Bernneke style rifled slugs. A "Cylinder Choke" will provide the best accuracy. Any choke with constriction of .020" or more can result in damage to the barrel. Our "Improved Choke" tubes have a constriction of .013" and therefore may be used with rifled slugs; however, accuracy may be compromised. Weatherby recommends slugs only be fired using a non-ported cylinder choke

interesting indeed.

ammo manufactures have a statement like this from the current Winchester site

'Designed for superior performance in all shotguns'

I have a box of Winchester that says it is ok in all chokes in print so fine I cant get a picture of it.

shotgun world has had the discussion many times and concluded the choke did not matter for safety.
accuracy-yes it matters

The slugs used would play a large role in the safety. There are big differences between brands. A soft lead slug going through a mod choke with .02 constriction wouldn't be nearly as bad as a hard lead slug going through a turkey choke with .06 or more constriction. Some of them are so hard they hardly deform at all when they hit something. Another consideration would be the barrel. Manufacturers are making many of the shotguns today with paper thin barrels. The barrels on some of my older shotguns probably have 3 times as much steel as some of my newer ones.

obviously some manufacturers differ in view. surprise, surprise.

here is one of the quotes from that forum about diameters of slugs.



"I first became a member of this forum several months ago, I have been telling people repeatedly that it will not harm a gun in good condition to shoot rifled slugs through a full choke. Millions of slugs have been shot through full chokes with no harm. I have also said that the slugs are smaller in diameter than the full choke and that the slugs are very soft lead. Just a few minutes ago, to refresh my memory on the numbers, I cut another slug open and measured it. This was a Remington Express 1 ounce 12 gauge rifled slug.

The slug was slightly irregular in its diameter and I got measurements varying from .685" to .691" at the widest parts of the slug. Most full choke 12 gauge guns are between .695" to .700" at the tightest part of the choke. So, you can see that the slug is actually smaller in diameter than the full choke. Besides, the lead is very soft and could easily swage down to a slightly smaller diameter if it had to."


I grew up in a shot gun state and have seen countless slugs shot through a full choke. again I am surprised. but it wont be the last I am sure.
