.223 Timbs for the CZ-52

Post by Grantness » 19 Oct 2008, 16:42

This is an interesting concept. 50gr .224" bullet at over 2000fps. :ponder:

Any thoughts on this cartridge?

Probably really inaccurate, but how much does that matter out of a pistol?

Actually I guess you could handload these for lots of different guns...http://www.eabco.com/reload02.html" onclick="window.open(this.href);return false;

Yep it's a piss poor copy of the BOZ. The move has put us farther behind then we had liked. We still are planing on bringing the BOZ ammunition to market, along with a blowback conversion kit for the 1911.

A bit more effort than the Timbs, and more along the lines of the BOZ:

Are CDS still being jerks about their patents?

I thought the BOZ was just a 10mm necked down to .224? Am I wrong? The Timbs is a sabot and will fire out of a normal CZ-52 barrel. The Reed Express and BOZ require special chamberings correct?

Im not really that impressed with these cartridges. They look to me like they are about on par with the 5.7x28.

The obvious advantage (besided case capacity) is that it's easier to rechamber and tune an existing gun from 10mm to .224 Boz or any of the other necked down cartridges than it is to develop a new gun from scratch for the 5.7x28mm and its longer-than-typical cartridges.

I see... So if I got a Glock 29...I could essentially (assuming a proper barrel existed) turn it into a pocket gun with 5.7x28 ballistics?

The BOZ is about 23% more powerful then the 5.7. As you can see the BOZ is slower but with a heavier bullet. I believe We can get allot more out of the BOZ.

NOPE not at all. Glock frames have a very hard time dealing with the 10mm recoil impulse.

They have a habit of self destructing. When the BOZ first came out CDS tried it on a Glock platform and the Glock blew apart within the first 1k. CDS founds three places were the Glock's design fundamentally failed.

They ended up going with a severely skeletonized 1911 with replaceable breach faces. The BOZ tor up the breeches with it's severe high pressure but short impulse. It would destroy the breech face and yet the power would drop off so fast it could not cycle the slide. The BOZ needs a blow back design just like the 5.7.

I know of a Gas recoil system for the 1911 platform that would work the best for the BOZ and it's on my mental drawing board.

I guess thats why they use the CZ-52 with that crazy roller design.
