New Idea For Low Report & Accuracy Cartridges.

I thought of a way to create a small capacity case out of a standard one. Present methods include reduced loads, fillers and adapters.

A case is made with about half of it being solid brass starting at the base. The case mouth, shoulder and some of the sidewalls are standard.

A 6mm PPC could be made from the front of a .243 Wincester! A 22 "Hornet" could be made from the front of a .223 Rem!

With the light new bullets available we could carry a .220 Swift in a populated area and shoot a load with say a 40 gr bullet with very little fast burning powder. Such a load would burn in the barrel and make a lot less noise.

I am quite sure that the existing transfer presses that make cases could make such cases.

What do you think?

Have you considered primer failure?

Sorry, but Palmisano beat you to it (sorta). Details are vague, but check out "The History of the PPC" in the Dec 2000 issue of Precision Shooting.

I would say,"strike that and reverse it". Thicker walls up front,so as to promote reliable ignition,as Mr.ricciardelli mentions.

Myself,I'm partial to a Marlin 39A and CB caps................

Lou's version is much more sedate,in it's severity. I anxiously await it's mainstream unveiling.........

I really am not concerned who thought of it first. Pamisano is not making a case for my .243 right now. It would be fun to experiment with the loads.

Primer failure? Maybe. Lets try it!

The idea to reverse was posted just as I typed the above.

OK but I can't see how the case could be drawn from one piece.

Cartridges have been made with front ignition so I don't see much of a problem with a flash hole half that length.

I have made some cases on the lathe out of brass. Maybe I will try it.

Basic brass used to be available in straight cylinder form. I could drop a piece of steel or brass into the case and run it into the form dies to make a case.

What did Lou Pamisano write?

He was very vague. There was a "drawing", but it's more like a cocktail napkin sketch. His idea is for a cartridge with a thick bottom end and a piece of cordite running from the primer into the powder. He says it will be better than the PPC, but at 4,5,&600yards. He's working with a German ammo company to get the brass. I've heard some people guessing that he's dealing with RWS, but IMHO, Horneber sounds like a better candidate. Their stuff is pretty limited production. I would think RWS would need to make like half a million cases or so to even consider tooling up something entirely new.

Thanks Lee,

I don't claim any original idea.

It's just an idea to be able to turn a larger cartridge into a small one at will.

It might be cool to be able to shoot ".308's" in a .300 Win Mag etc.

I like the part best of a low report varmint cartridge. The Hornet's really don't shoot well on average and there are so many .223's now.

The easy way seems to be using "basic brass" with a insert.

why dont make a chamber in a piece of brass formed for 308w and use a 7,62*39 or 30us carbine. 223 camber for 22-250r.
Make 5 of them to fill a mag.

Cabela's sells a "Multi-Caliber Adaptor." Go to their web (www.cabelas.com) page and follow this path:

Storefront > Hunting / Optics > Shooting Accessories > Tactical / Military / Enhancements > You are here: Multi-Caliber Adapters

Looks like a piece of steel that you put in your chamber allowing you to shoot a different chambering. They don't offer much of a selection, though. I also wonder if the use of one of these adaptors would leave marks in your gun?
