Brenneke KO Slug question

Anybody try to use these? Sucessfully? I bought some and fed them to my Benelli Super Nova with the 18 inch smoothbore. Great accuracy but no extraction. Shells stuck in the chamber. I bent the rims off with the extractor claw beating them loose. Switched to Winchester slugs and it cycles properly and each time. Guy at the gunshop told me that they are tight to extract and he spent a half hour in the field once removing a shell from his Remmington 870 while his deer was off somewhere being wounded.

Someone use these in another shotgun with no troubles? I can dig out my old Mossberg and put it back togheter maybe (safety broke, works but no safety so I put it in the closet) or just bag them. Maybe a single shot?
 
I've seen one other report on the board about sticky extraction and feeding problems with KOs. Haven't had one iota of problems with them here for years, in a dozen different pumpguns (mostly 870s), feed and fire just fine, extact and eject no problems, and hit what they're aimed at.

Heard from a supplier a few months ago that Brenneke was switching to a European company to load the KOs, had been using Kent in the states but they were having trouble keeping costs down. Could be the troubles stem from a different manufacturer- who loaded the ones you are having troubles with??

Best bet in your case is to use another brand, it seems...

The shells I had troubles with were Kent's I got some others that are RWS Rotweil's and they worked fine today. The extractor did bend a lip up on each shell. Remmington Green sluggers fed fine with no extraction troubles but Winchester's had some problems as well. They were higher velocity and did have more oomph. There is not much clearance on the barrel for the ectractor but I don't think that is the issue. The chamber might be tight I don't know that much about shotguns.

I did pick up some Brenneke Tatical Home Defense low recoil to try. 1100 fps at 25 yards where the Winchester's were rated at 1400 & 1700 at some unspecified distance.

All but the Remmington's were accurate.
 
I borrowed a Mossberg and they ran fine. It seems the lugs on the Super Nova gets tight with some ammo and makes cycling a royal pain. Now I have to see if it is a gun problem or a break in issue. I think it will go back as it is new.
 
These are the ONLY slugs I've ever used (Well, Brenneke, I don't recall if the KO name was used all that time) in 35 years of shooting. I've never owned anything but Mosberg 500s, and they always have worked fine.
 
It is the gun. The locking lugs are tight with some shells. Some spent shells are harder to freehand turn the boltface than others. Low power/recoil Home Defense loads work fine, higher velocity standard shells tend to jam. Good thing I did not use 3 or 3.5 shells or I never would get it apart.

Going to try a polish of the boltface and lugs. Most I have seen in pics are shiny not black oxide, maybe that is the reason?

It shoots too well other than the extraction to give up on yet.

I did get my hands on a Mossberg and the same shells worked fine without any problems. The Mossy like most shotguns I have seen don't have a rotating/locking bolt similar to a Mauser rifle bolt lockup for want of a comparison. That's probably why they eat these loads without any indegestion.
 
Ralph,

I've used them in a Winchester 1300 and a FN Police Shotgun (1300 clone), which have rotary bolts. They work fine in both those guns. Sometimes it is a dimensional problem between the chamber and the ammunition in question- I have one 870 barrel that just will not run Fiocchi 1- ounce loads when it gets hot no matter what, it's been honed more than once and it just won't run rapid fire with them. Slow fire it's OK, but run a Rolling Thunder drill and it locks up after the first magazine full. It's just that one load it doesn't like for whatever reason, might just be that one lot number, I don't know. I just don't try to run that load in that barrel any more.

But I know why you want to work on getting KOs to run. They shoot well and don't cost an arm and a leg. If the gun's still under warranty I'd send it back were I you...

KO problem KO'd

Fixed the problem with the sticky removal of KO slug empties. The chamber was too tight. The chrome plating in the chamber was a little rough and tight.

My fix was to take a spent shell that was tight to remove with my fingernail and buff the chamber until it fell out. 400 grit emery cloth then 800 grit followed by JB bore paste lapping then a powerdrill with a .308 chamber brush to power lap the chamber mouth. Now it feels smoother and looks smoother. Shells come out now that had before required me to slam the butstock down on the concrete floor while holding the slide.

I first thought it was the shells as the lower power shells worked fine and Winchester's did at first. Then they started to stick. Now I went through a half box of slugs with no jams or bent rims.

Now this is a decent shotgun. Kinda sucks to have to do all that to a new in box weapon however. My old Mossberg worked fine but the recoil is a lot more noticeable in it compared to the Super Nova.
 
Dad loves them!

I shoot the old winchester rifled slugs out of my A-5.The gun held the tightest groups with them.My father shoots ko's out of benelli M-1.No probems and very accurate.Above all that they run great sales on them.
 
I have had this problem with a new Remington 870 Slug Gun.

I just stopped trying and used Winchester and Remington Slugs.

No problems with American ammo at all.
 
You might want to try the new Federal "Tru-Ball". It has given me amazing accuracy and I'm hard to amaze. No kidding grouping with a red dot sight is consistently 1/3/4 or less at 50 and less than 5 at 100, from a 20 inch IC barrel. I didn't think that was possible.
 
I have been shooting them for years. My 870, Mossberg 500, and my Browning A5 Magnum all function perfectly with Brenneke slugs.
 
The Brenneke 3" Rottweil 1 & 3/8oz slugs and the Winchester Power Point High Velocity 2.75" 1700fps 1oz slugs work flawless in my 870's. Highly recommend them.
