Even More P90 Misc

In the 1950's Czeckoslovakia modified the rolling-lock breech system of the German MP-40 (also used, we are told, in the P-5) to a semi-auto Military pistol; the CZ-52 chambered for the .30 TOK, also known as the 7.62 X 25MM.

Well, no. The MP40 is straight blowback. The Stecke-lock roller locking of the Cz52 is more akin to that found on the German MG42 and developmental Stg-45 assault rifle designs, said to be German developments of prototypes taken during the invasions of Poland and Czechoslovokia.

The German Walther P5 pistol is a development of the wartime P.38 with a lifting wedge type locking system- though if you meant the H&K MP-5 submachinegun, yes, it does indeed have a roller-locked mechanism.

I recently bought a CZ-52, and it is a well made, interesting pistol. The 7.62X25 is a peppy little round indeed, and apparently can be reloaded with a 55 grain saboted .223" (5.56MM) bullet and stepped up to around (as I recall) around 2,300FPS - not bad for a sidearm!

The 7,62x25 is indeed *peppy*, a very reliably fed cartridge due to its bottlenecked configuration, and very suitable with reloading with bullets of .308 to .311 in diameter, both lead and jacketed...and the 109-grain tracer bullet of the .30 carbine works nicely, too.

One might speculate that simply necking the .30 TOKAREV to 5.56MM might provide similar carachteristics to the 5.7X28MM developed for this new system. I would not be the least bit surprised if that is essentially just what it is.

Pretty close, though there are some questions as to whether to lean toward the light/fast 45-55 grain .224 bullets of the originam M16 M193 ball ammunition, or to switch to the 62-grain M855/SS109 style bullet [or heavier] for better penetration. Considerations of barrel twist rate arise, as they have with the 5,7mm MMJ, the .30 carbine cartridge necked to take a .224 bullet.

The .223 Timbs is the result of a co-development between Quality Cartridge and Joseph Timbs. It is the American answer to the proprietary .224 BOZ, bringing the CZ-52 into the new millenium. The .223 Timbs is a special loading of the 7.62x25 round for use only in the CZ-52 pistol. It consists of a sabot like the Remington "Accelerator" pushing a 50gr bullet over 2000fps. Concept was for devastating multi-purpose round, useable for small game, varmits, and defense. Accuracy has proven to be on-par with traditional rounds fired from the same pistol, and terminal ballistics are quite impressive with initial tests showing devastating expansion from the varmit-type bullets.

My old C96 broomhandle serves me well; The CZ 52 and Russian TT-33 Tokarev do as well and can handle MUCH higher pressure loads. And that 71-round drum of Shapagin's PPSh-41 submachinegun offers some interesting possibilitries, too:
