Brenneke KO slugs

Hello to all.
Has anyone had any experience with the Brenneke KO (non-sabot) round in a rifled barrel? They advertise them for use in both smooth and rifled barrels. I have fired them out of my 870 smooth bore, and had decent results. I now have a Hastings rifled barrel, and am wondering if anyone can give me some feedback.
Thank you all in advance

if its a rifled slug you dont want to use it in a rifled barrel. Ive "heard" that brenneke syas they will shoot out of both smooth and rifled but I just dont see how they could get around the rifled to rifled extream twist problem myself. My rifled slug barrel absolutely loves the Lightfield saboted slugs. Dots the i's at 100 yards. Also been hearing really good things about that new winchester cx slug as well.

If you shoot a rifled slug out of a rifled barrel you end up getting so much spin on the bullet it flips.

I shot some in NEF rifled barrel,Stabilized ok........
But they lead the barrel rifling as the lead is soft.
That is why most use sabots in rifled barrels as the
plasic doesn't get stuck on the rifling. These are a good
value for decent price. If you have to clean lead,
do it same days you shoot, and use a copper
choirboy scrubber on you wire bristle rod end and gets
llead cleaned out with a little scrubbing.ED

OK, I took the bull by the horns and tried it for myself. I'm sold. These are giving me almost the same accuracy out of my Hastings barrel, that I get with any sabot load I have tried. (2 1/2 ' at 75 yards, iron sights) At one third the price. No sign of any leading after firing 20 rounds. At the $2.69 a box I paid for them, these are the bargain of the century. Just bought 10 more boxes. I'm set for at least the next 5 years.

Tweesdad--The leading I noticed was just specks, not
smeared on heavy. Was going 500 fps faster than you
as I took slugs out of cases and used them for our
12GA FH testing, so that would account for specks.
Your rifled barrel is a super good one to fire that many
times and still be clean. Don' t lose it. Your smoothbore
you tested them in, what choke did it have. Ed

Hubel, How is the Bren's solving the rifle to rifle over spin problem? Ive seen where MANY have tried doing this and the bullets go all over the place. Sometimes its because of the rifled bullet being rifled to right hand twist and the barrel left hand or vise versa. Then in others its flipping because of over spin. Just curious how these seemingly magic rounds are accomplishing this is all.

Ok---Bullets/slugs flip, etc ,if they are under stabilized.The twist in my
NEF Ultra Slug Gun is 1 to 35, hardly considered fast.
Bullet/slugs are stabilized in two ways, one spun by rifling
or two they are designed front end heavy. The latter being accomplshed
by hollow bases. But not all barrels fit good enough to some
hollow base slug to get them started straight just as they leave barrel.
Choke problems, to long freebore, Noe the Brenneke and others
for smoothbores have a wad locked on the back as well as hollow base
and wad material being lighter than lead also aids stabilization.
Thr so- called rifling on smoothbore slugs don't actually impart
any great ammount of spin, theytjust are ther eto crush easily
when sug goes through chokes.So if it is fired in rifled barrel it will
spin like any other bullet in rifled barrel. Barrel must be
the right size.The KO has the wad pinned into hollow base.
to slug so it spins with it. And if barrels are right should give results
like Tweesdad got. Now some rifled and smooth barrels are built way
too big all the way up to .745", when rifed should be .729" like
the NEF, the heavy one I have on 210 Savage, like others
I am experimenting with.Some cobinations of barrels and short stubby
hollow base slugs can be a pain, but for most part Brenneke
is better than those. So is the heavier hammerheads and
buckhammersEd

Ah so the wad is acting as a sealer and also used to help establish a better contact with the riflling as well? I know that what they used to have (Dad called them Pumpkin balls) the old Remington rifled slugs, I tried 5 out of my Mossburg rifled barrel and Lord have mercy what a funny thing that was. One in the target (sheer luck) the rest I have no clue where they went. The one the hit the target told me that it was tumbling (had a VERY elongated hole). I know that the rifled slugs dont get a whole hell of a lot of spin out of a smooth bore. But it seems to me that in a more tighter toleranced rifled barrel, that it would achieve much more contact. Just trying to wrap my head around it is all. If you have a conical lead projectile, such as most rifled slugs are, with a curved rifling cut in to it, making contact on an equally or even greater curved rifled barrel, then physics say that you will get twice the spin. While this factor in itself may not be a bad thing, given different weight values, balance of the projectile, and so forth, all things being taken into the equation seem to point this as a bad thing. Now if what you are saying, and I think it is, is that the rifeling on the Breny is so soft that rather than making strong contact and causing effect, it simply conforms to the rifling in the barrel therfore just creating better contact and only spins as much as the barrel allows. My guess would be that the older slugs were made of a harder lead so the slug would make its own physical force as well as the barrel's spin. Even us old dogs TRY to learn new stuff Thumbs up

That's right slug and wad just catches rifling in barrel and follows it.
The Brenneke seemed just as hard as an older foster
I have here by the thumbnail scratch test., and along
with locked on wad it seems to work. Now we've seen some
smooth barrels with right size that shot the fosters pretty good,
but a lot of barrels with backboring., long freebores, wrong
chokes can shoot screwy like the on you described.
Rust can be a problem. Here in MI high humidity it's a pain
to keep them bores shiny. Rough surfaces don't help
slug shooting.Ed

Yeah Im sure a wrong choke can do that... But my experiance was with my Mossburg rifled barrel. I dunno, maybe it was just a fluke or something. Just know ive also heard many simular results from people mistakenly shooting rifled in rifled barrels. I did have one of them Rhino screw on rifled chokes on one of my old shotguns (cant remember which one it was, go through shotguns like underwear) and the lightfields worked wonders with that as well. I would say I WANT to try out those new Winchester cx slugs... But I dont think WANT would be the right word. That damn slugger HURTS my poor old shoulder. I simply dread taking the damn thing to the range anymore Brick Wall,) sucks gittin old sad But I have been seeing some mighty fine things being reported on them. Buddy hit a FAT 2 or 3 year old Doe here in ILLinois (shotgun only state) last year when they were being market tested and WOW did it split the cage. Folded her damn near in half. Would HATE to see what it would have done if he had hit her square on the shoulder. He hit her dead behind the shoulder right through both lungs. Didnt even take a step. Got knocked over, shook, died.

I've often thought that the old fosters would have done better
if they'd had wads locked to the bottom.. Your right, some
of these saboted slugs are really doing a good job.
Most guys though are hollering about the price, and it is
hard to see why they cost so much.. Ed
