The nominal bullet weight is 85-86gr, and from a pistol velocity can range from 1400-1700fps.

New commercial S&B ammo can be found for around $8.50 per box and is the best choice in my opinion.

The CZ-52 is robust and accurate. It will attract attention at an indoor range. Everyone wonders what the loud flame-belcher is.

The cartridge its self is "similar" to a 9mm x 25mm case that is necked down to accept the 7.62 bullet......much like a .357 sig.
Thats where you smoking velocity ratings come from, big charge with a little bullet...we have chrono'd some at 1650 + fps...

Shoot well

One thing needs to be said about the CZ-52. They're known for killing firing pins, especially if you dry fire.

Mike is absolutely correct. The firing pins in some guns are too brittle and may break, due to alot of dry firing..also some of the decockers act as a second trigger if the mechanicals are worn.
New and improved parts, rollers, firing pins, etc...can be had from Makarov.com....these guys carry the best quality or nothing at all.

Info on these guns can be found all over the net, but some of the better pages are linked below...including reloading info....

Hope this helps....Shoot well

Based on experience with both the CZ 52 and the Tokarev(both 7.62x25 pistols), IMHO the Tokarev is a better design and is easier to field strip. The CZ has trigger slap and pins are always moving out of position. I view the Cz as way for the Czechs to demonstrate national individualism in the face of Soviet domination. Note the Czechs went to the Browning lockup as was used in the Tokarev with their CZ 75.

If you want to shoot this caliber get a Polish Tokarev(they are still around) as first choice and if you can afford it, get a Cz 52 also, mainly for the uniqueness of its design.

OTOH, the Tokarev is less robust, and if you feed it submachinegun ammunition or hot reloads it has, supposedly, been known to cause really bad things to the gun and people holding it.

The CZ-52, while not immune to catastrophic failure (especially from bad surplus ammo), is much stronger. Also, if you're looking to handload the 7.62 and get some screaming velocities, I'd do it in the CZ, not the Tokarev.

The supposed superior strength of the CZ 52 over the Tokarev may or may/not be urban legend. I have seen this posted before and I challenge those who claim it to prove it without tests and /or good scientific analysis.

Months ago this claim came-up(I think I made it) and I got a long E mail from an engineer that had data suggesting that the reverse is true,ie., that the Tok is stronger than the CZ.

This I am certain of, if you use current manufacture S&B ammo in either gun you will have no problems. Both pistols are 100% reliable with this ammo in my experience.

The difference in "strength" or robustness really comes about from several factors...

The CZ-52 uses a roller locking system that helps absorb and buffer the effects of the 7.62x25.

The CZ-52 was designed specifically around the very hot Czech ammo, which according to Small Arms of the World is loaded to about 20% greater pressure than the Soviet loads.

The Tokarev, being designed around the older Soviet-power round, doesn't have a recoil spring of adequate power to handle extensive shooting with Czech ammo.

I've seen two Toks that have been shot extensively with Czech ammo. Both showed evidence of moderate to severe battering of the frame and slide. These were both produced during WW II, when the Soviets were turning out weapons as quickly as they could. I have no doubt that the quality of the steel wasn't up to either pre or post-war standards.

However, I really think that the Tok would handle the Czech ammo a LOT better if a stronger recoil spring were fitted.

The CZ-52 is much easier to field strip than the Toke, no offense intended. You pull down on the latch and remove the slide. You then push with your thumb on the roller assembly while holding the slide back until the barrel comes out. The grips pop off with a screwdriver of the base-plate of the magazine. A CZ can be stripped much faster than the Toke.

The Toke is a simpler design, to be true, but the ease of field-stripping goes hands down to the CZ.

The reason you see the rebuilt CZ's on the market is because they were used for 25 years before they were rebuilt. Most 1911's were rebuilt on the same rate, some more often.
