Has Anybody Wildcatted Brass Shotshells

After reading this forum's post and looking at my collection of brass shot shells, I was wondering if anyone has ever necked down one to form a new cartridge? With the current trend of short fat cases, either the 12ga or 16ga brass shotshell would be an interesting and probably ultimate short fat case. How about a 22-16ga varminter???

There is a customer coming over tomorrow with a Win 12 ga lever gun. He had a .700" cal barrel made by PAC-NOR, and a custom reamer. I am supposed to fit and chamber the barrel. I don't remember the round name, but it is an old obselete Win cartridge. Something like a 7-something by 1000. I'll know more about it tomorrow. As far as going smaller, I would be real careful. The cases are not designed for high pressure, so necking it down very far will be difficult, (from what I can tell).

The .70-150 Winchester is (was) made by shortening and necking down a 12 Gauge brass case. It is mentioned in Gun Digest 6th ed.(1952) p173; Cartridges of the World 8th ed, p144; Herschel Logan's book: CARTRIDGES (my copy is 1959), p154; and other places. In the last couple of years, reproductions have become available (at least at gun shows here in Minnesota).

In vol I of CARTRIDGES by Fred Datig, there is listed a 15 x 40R Straight and a 15 x 49R Straight---apparently made from 28 gauge shotgun brass cases (page 93). Also listed (page 94) is a 15.8 x 40R Straight and a 15.8 x 50R Straight---made from 24 gauge shotgun brass cases. These four are really nothing other than brass-cased slug loads for shotguns.

I received a Win 1887 12 ga shotgun to day to rebarrel and rechamber to the 70-150-1000 Winchester. I saw it in Cartridges of the World as the 70-150 Win. I guess the 1000 is the 1000 grain lead bullet going 1300 fps. It looks good, and out of a lever gun is even better. The customer has a Martini chambered for it, and his friends make up 5 other guns. The cartridge is wasome. I'll try to put up a picture.

Here is a link to the pics

Looks like it would make a fine pistol round.

If they wanted stronger brass, they could always start with a 50BMG.

slightly off topic, but 577 nitro looks like 16 gauge brass

I believe that 24 gauge brass is used by some to make .577-450 Martini Henry cases. I really think the idea has merit for certain uses. Low pressure rifles from shotguns: you install an insert which forms the rifled barrel and the front of your chamber. Now you have a high volume/low pressure rifle (preferably big bore) rifle with no modification to the bolt or extractors or such. The only catch is that you are working at BP pressures, and that is not all that bad. Cape guns, anyone?

Really, the idea sounds workable. I wonder if it has been tried.

I've used 32 ga. CBC brass shotgun cases to form the following;

.56 Spencer
.56-50 Spencer
.50 U.S. Carbine
.50-70 Govt.
.50-90 2 1/2" Sharps

A friend of mine is using the same to form cases for a European rolling black cartridge equivalent to the .50-70 Govt. He also uses their 24 ga to form .577 Snider and .577/.450 Martini.

When you use CBC cases they are semi balloon head and need to be annealed to avoid splitting. Other then it having berdan primers, it works pretty well for black powder pressure rounds.

Hi jnrifleworks,

The 70-150-1000 looks like the cartridge I'm wanting my next Encore barrel to be. Can you give me the specs on the bore/twist rate and which barrel maker I might be able to get one from?

Thanks
doc-and

doc-and,
Call PAC-NOR. They made the barrel. I would have to go look to see the twist rate. I don't think there is much to choose from twist wise. Their website will tell you.
541-469-7330
PAC-NOR's Website
I don't think I would put it on an Encore. [Eek!]

I setup my own site for selling my cast bullet lube, http://www.lsstuff.com/lube , and moved the personal stuff over there also. http://www.lsstuff.com/howdah

I turned down some 50 BMG cases to make these,
They are sitting next to 475 Linebaugh 1.6" and 454 Casull.
I have also played with just cutting down some CBC 16 ga brass hulls and turning the rims almost off on them.

I know this was a couple of years ago, but it has been brought to the top. So FWIW.


Pac-Nor 470 blank turned down for 470 NE insert into Belgian Antique 12ga.

With NECG express sights on the rib.
It's sat 90% finished for awhile now, but I've had it out to the range recently trying to get the left barrel regulated with the right. I ran a couple of dozen rounds through it on the last outing and got stupid. I couldn't remember what to do next, so I packed up and went home. I'm about 6" apart at 50yds now, but hope to get it finished next time out. Then I just need to build a new extractor.
