evening, fellas.  among the many handgun cartridges i'm currently plugging away on is this cz-52.  i decided to use the hornady 90 gr. xtp so went with their data as a guideline.  they developed their load in a cz-52, as well.  having a lot of h110 on hand and with it being the top performer from their data, that was the natural powder choice.

they print a max of 14.2 grs. for 1700 fps.  with my last development, i reached 14.0 grs. and my handgun was averaging 1490 fps.  as i was running these loads over the chrony, with a seating depth giving a 1.333" col, i thought maybe i had seated things to far out, producing less pressure then necessary to achieve hornady speeds.  but when i got home, i saw hornady's col was 1.385".  if i seated that far out my pressures would drop and my velocities would suffer even more then what they currently are.

part of me is wondering if that 1700 fps is even realistic.  it would appear certainly not with their 14.2 gr. max suggestion     ...     in my handgun, anyway.

i'm curious what you guys loading for the tok are using for components.  your col's.  velocities.  i'm sure 14.2 will get me over 1500 fps with this bullet and i'll certainly be fine with that but was wondering if there's folks out there actually seeing 1700 fps with this weight bullet in a cz-52.

much appreciated.  korey

I've never loaded for the 7.62x25. Just didn't want to screw with a bottlenecked handgun cartridge, but might be starting. Have two guns chambered that way, a CZ-52 and a Tokarev.

Looks like I'll be using your posts for a reference.

My favorite CZ-52 load is extrapolated from the Accurate Reloaders Guide dated 2004. They list a Sierra 85gr RN with a top load of 13.1gr of Accurate #9 @ 1735fps! I had a bunch of Hornady 90gr JHP bullets, so adjusted the load down to 12.2gr.

Consists of: Starline brass, 90gr Hornady JHP, 12.2gr Accurate #9, and a Win SP primer with a LOA of 1.300".

Here's a puzzle: the reloaders guide specifies CZ 52 only, however, they list a barrel length of 9".

My specified load works very well in my Cz52, with no failures to feed, also the brass looks good (the ones I can find after firing).

My CZ is equipped with a 16.5 lb recoil spring and a machined aftermarket firing pin from http://www.Makarov.com.

I don't think that the above loads would treat a Tokarev 33 very kindly. The Europeans loaded the 7.62X25 cartridge for a lot of different firearms, including Czech and Russian sub guns, the Tokarev, and of course, the CZ52 - all with different power levels. I'd hate to think of a Mauser C96 after firing any CZ52 load.

I found some Portuguese loadings with an 85gr bullet @1650fps which work well in my 52 - with no bbl length specified.

If in doubt, go to http://www.accuratepowders.com for the latest loadings for the 7.62X25..

no better time to start then now, charley.  always good to have more folks to compare notes with, too.  the tok's now my 3rd bottleneck handgun round i've been tinkering with.  want to add a 4th soon (.400corbon for my 1911).  they're each pretty straightforward.

klallen, I don't have a chronograph, but if I had to give it a SWAG, I'd estimate about 1550+ out of a CZ52. Not much help, I'm afraid..:confused:

Hey fella's...

Does either of these Sierra or Hdy bullets have cannelures?

I was loading this round 4-5 years ago and gave up on it. I was too lazy to order any of the bullets mentioned, so I hung it up.

The only thing that I could find locally was the Speers 110 grain along with some half jackets that I picked up somewhere.

The problem that I was having was bullet backset. I could never get a crimp that would hold it. I tried about everything to no avail.

Thanks

And course, that cz slung my brass into the next county so there was a real deficit going on there.

Since then I've always used Mil Surp.....

worked up another batch of 14.0 and 14.2 grs. of h110 and seated things deeper by 3 hundredths, to your 1.300", 30-06user.  will see what the combo of added powder and deeper seating depth offer over the chrony.

nope, sprue.  the 90 gr. hornady xtp i'm using does not have a cannelure.

klallen, I'd really be interested in your chronograph results. I have some H110 on hand to try..
