16b. Brennek Slugs?

[ohiochuck]

Any word on the re-introduction of the Brenneke 16 ga X 65 mm (2 1/2") "Classic Slug" in Th USA?
Thanks!

It just so happens that I corresponded with them yesterday ...

"The container will leave Germany about mid May. It takes about two to three weeks for it to arrive, clear customs, and then sent to our loading company. Right now I estimate deliveries should begin about late June or early July."

Whom will be carrying them?

[Büchsemann]

I forgot to mention that Brenneke's US operations are going through the same run on ammunition that our other ammunition manufacturers are dealing with. It certainly is nuts ... but expected.

Looking forward to testing them.

Seems from an earlier conversation that the distributors will be the same as those carrying other Brenneke ammunition today so Midway, Cabelas, Gander Mountain, and Graf and Sons, to name four, will probably be carrying them but we'll have to wait and see.

Will the 16 b. 2.5 inch Classic Brenenke slug weigh 1 & 1/8oz and will the speed be slower than the 1460 fps listed (I assume the2460 fps is a misprint)?
Thanks!

Brenneke Classic Magnum 16 Gauge, 2 3/4" (Per 5)

The incredible Original Brenneke Golden Slug teams all the power and reliability of the Original Brenneke 12 ga 3" Magnum, but with specialize design and construction for the unique demands of today's rifled slug barrels. Broad ribs on the Golden Slug grab the barrel's lands and a special coating which dramatically reduces lead fouling for shot after shot precision shooting. Brenneke's patented PowerWad with its build in piston action is fitted into the Golden Slug, too, for smoother firing and outstanding trajectory. SPECIFICATIONS: Gauge: 16 GA Type: Slug Length: 2 3/4" Ounces: 1 1/8 oz Shot Size: Slug Muzzle Velocity: 2460 fps

Jim,

I'll have to go back in my e-mails from last year but I believe the 65's are going to be really close to the current 70's. The specifications that you show sure look hosed up, where did you find them? Brenneke's USA website notes their 2 3/4" 16ga "Magnum" as doing 1580 fps at the muzzle. They have the slug weight at 1 oz/415 grs/27 g. I have the feeling the new 65's will be a tad slower. They will be using the same slug.

Mark,
Your info looks more reasonable than mine. Did a search on the net and located this info or misinfo. The 1 oz weight seems more reasonable than the 1 & 1/8 oz. I listed.
Thanks!

This is a little OT but I was given several boxes of Remington 2 3/4" 16 gauge foster slugs. I removed one of the slugs and measured the opened case and it is barely over 2 9/16" not 2 3/4". Is there any reason not to use them in one of my drillings with 65 mm chambers? I dropped the slug down the barrels of four drillings and on some it fell through and on the tighter choked ones the slug stopped with about 3/4 of its length sticking out of the muzzle. It was easily pulled out with slight finger pressure.

Thanks,
Roger

I will attempt to answer your question. I own 2 drillings: a JP Sauer 12x12 x .222 Remington & a Seimpert & Kreighoff 16 x 16 x 8x57R. The Sauer was made in the 1960's and has 2.75 inch shotgun chambers. The Kreighoff was made in 1930 and has 2.5 inch chambers. I only use low pressure shotgun chartridges in the 16 b Kreighoff such as the American made RST shotshells. I will never attempt to use American 16 bore 2.75 inch shotgun slugs- because the pressure is much higher than I believe my 1930 drilling was designed to handle. I believe that 2.75 inch cartridge use in the 2.5 inch chamber might cause serious problems. With the Sauer made in the 1960s I might use American shotgun slugs- I believe the drilling was designed to handle higher pressure shotgun shells. I have only used Brenenke slugs in the Sauer. I have used American Winchester AA shotshells in the Sauer. However my assumption is appropriate only for me. I would suggest only using cartridges made for that chamber and only the appropriate pressure cartridges that your firearm was proofed to safely handle.
Others need to comment.

Does anyone know the pressures generated by the Brenneke shotgun slugs in 12 b. 2.75 inch; 16 b. in 2.75 inch and possibly the presssure of the new to be released Brenneke 16 b. 2.5 inch shotgun slugs.
I believe that the American shotgun rifled slugs generate between 10,000-13,000 PSI. Check this site http://www.saami.org/specifications_...wnload/209.pdf

Addressing the comparison between the early nitro steels and today's steels as they relate to gun barrels and receivers would lead to a rather complex and technical discussion to include material properties, construction, and measurement to include the measuring of hoop stresses, pressure curves etc. As to the steels themselves, developed by Krupp, Böhler and Poldi around the turn of the century, they are every bit as capable of withstanding the pressures seen in today's loads but the devil, as always, is in the details. For example, a popular chromoly steel used today for receivers and barrels is 4150 which has a hot rolled tensile strength of 65,000 to 75,000 psi. One doesn't necessarily have to understand how pounds per square inch is measured to understand that if the wall of a 4150 barrel where machined too thin for the pressure developed by a particular load, the barrel would blow; most can pick this up intuitively. Anyway, this explanation could go on.

The deal with a chamber being too short for a particular shot or slug shell cartridge is to understand how the location of the "forcing cone" between the cartridge chamber and the bore diameter plays into the cartridge length. The cartridge wall, be it cardboard (back in the day) or plastic, has a thickness i.e. material strength. When the cartridge is discharged the folded crimp unfolds or the rolled crimp unrolls this thickness. The proper cartridge length to chamber length should allow this thickness of cartridge wall to lay flat against the chamber wall thus allowing the projectile (shot column or slug) to enter the bore without interference. If the chamber is too short this thickness of cartridge wall will rest against the tapered forcing cone and to whatever extent block clear passage of the projectile to the bore. This interference creates a spike in pressure that is generally felt as an increase in recoil. Fortunately I haven't heard of guns blowing apart on a regular basis but pushing pressure limits on firearms is not a safe practice and of course not good for the gun, old or new.

A good series of articles to read on the subject of barrel steels, proof pressures and chamber lengths to include a lot of test data is that written by Sherman Bell titled “Finding Out for Myself” and published in the Double Gun Journal. The topic of long cartridges in short chambers is discussed in Part V "Long Shells in Short Chambers" (Double Gun Journal - Winter 2001)

I forgot to mention that if you look and the cartridge and chamber diagrams (starting on page 13) in the ANSI/SAAMI standards, for which Jim has attached a link, you can see what I have tried to describe about the relationship between the cartridge unrolled or unfolded length to the start of the forcing cone. The diagrams show the overlap of the max uncrimped cartridge length into the begining of the forcing cone not to exceed .010".

Graf & Sons sent an e-mail today saying that they will not carry these. Hopefully the others will.

I'll ask Brenneke if they can give us a clue as to the retailers that will be handling the new cartridges.
