P64 to Range Today.

[fknipfer1]

I took my P64 to range today and shot 50rds of 93gr Missouri Cast lfn bullets with 3.6grs of W231. The gun shot reallly nice with the 19# spring in it only compaint is SA is just too light with 19#'s for me. Didn't have any light strikes but I was using WSP and those are probably easier to set off than Russian primers. Accuracy was very good at 7 and 10yds I did shoot any other distances because trip was to check SA Springs. Only had one glitch and that was on one last round it didn't hold the slide open. So that to me tells me I am right on the borderline with the 19# and I should use a 20#. After lunch I am going to gunroom and put the 20# spring in and clean gun.

May try it again tomorrow with 20# spring because to use this gun as a carry gun it needs to be dependable and comfortable. If I can ever find any Hornady CDI's in 9mm Mak thats what I will carry in the P64. It has a real nice size and can be carried easily.

If only someone would make a limited production run of the original Polish milspec 71 grain FMJ's we wouldn't have to tweak with springs.

I thought there never was a 71gr bullet ever made for the 9X18 Mak, when they first started playing around with the guns they were using a 32cal 71gr but did not accept it. That's what was told to me so I have to believe it.

fknipfer1, it's as it has been said. The "actual" Polish manual says the projectile weight is ~92-93 grains (6.0 grams). No 71 grain bullets. I can't even imagine what a 71 grain, .963" diameter bullet would look like. I don't think it would sit in the case right and it'd be cock-eyed as there wouldn't be much bullet there to seat. Either way, I don't guess it matters, but I feel D.R. Morse was wrong in his little pamphlet of the P-64.

[fknipfer1]

Most .32ACP calibers are 71 to 73grs. and at a diameter of .312 so your bullet couldn't be that small. So you can see what the difference is by looking at one of them.

According to this web page, Sellier & Bellot produced a "hot" 4.5 gram (~69 grain) sintered bullet in 9x18 Makarov specifically for the Czech CZ82 platform.

Interesting reading, especially given that my first C&R pistol is being delivered tomorrow - a CZ82!

[juniustaylor]

The "hot" round was a practice round. Sintered = frangible. It was suitable only for practice and only in a polygonal rifled barrel as the CZ82 has. Is it possible, yes... is it intended for actual self defense / wartime use, no. By pressing the iron powder together, it wouldn't be as dense and you could get it to be about the right size as a 90'ish grain bullet.

I did read that they used this bullet as a service round, I think that's ridiculous.

The available information, scant as it is, seems to disagree. What we have seems to indicate that this was intended to be a service round. Yes, I know that sintered is (essentially) frangible (not all frangible rounds are sintered but a case can be made that all sintered rounds are intended to be frangible).

Now, at some point more information may be available and could positively peg it as a purpose intended practice round but, again, the current best info says otherwise. If you have a better source than the referenced Czech manual, I'd be happy to see it.

Even today some sintered rounds are intended for service use. In the civilian arena, sintered rounds are generally intended for practice rounds and are designed to disintegrate into powder when striking a hard surface such as a steel back-plate. But that is not the sole purpose. Most sintered rounds intended for service use are, however, intended to have lower penetration.

By pressing the iron powder together, it wouldn't be as dense and you could get it to be about the right size as a 90'ish grain bullet.

No disagreement there.

Yeah, they forgot to consult me too.
