CZ-82 not Polygonal rifling?

[Triplanetary]

I just bought a CZ82 with a US made barrel*for $239, same company was offering an original with polygonal barrel for $199. I don't know if I get the better deal or not, I will be getting another (poly). I am very inexperienced anyoneone have inpput on the barrel differences.

Unless you are a reloader who wants to shoot unjacketed lead bullets through your gun, I don't see the reason to get a CZ-82 with a replacement barrel. Polygonal barrels have a longer life and are supposed to be more accurate. Having the original barrel also increases the collectors value of your gun.

Even with Unjacketed lead, it only matters if you

THEN (as in after shooting lead, WITHOUT CLEANING THE LEADING)

Shoot jacketed bullets

I've read many accounts by new owners of CZ-82 pistols who mistakenly believed they chanced into a pistol with a worn/shot-out barrel, not realizing the barrels were in fact polygonal rifled.

I passed the first time I'd seen one because of this, then I learned it was called "oval" rifling. Different than polygonal rifling -- you can clearly see the lands and groves in a polygonal rifled Glock or other gun.

Use the search, there are threads about it here.

Great little pistol enjoy mine, but I got it mostly for the unusual barrel. If you put a bore light in the chamber and "walk" the reflection up the side of the barrel you can see it "spiral" as the bore diameter changes to make the twist.

When I was ordering at the JG site I just assumed the slightly more expensive one would be better for some reason ( a naive assumption). As it was the the thing arrived almost 100%, tiny bit of finish wear on left front of slide. It gave off lots of oil, leaked in fact. Does the CZ USA versions of the same gun have different barrels from the the surplus ?
I was going to get another one. Considering the difference in accuracy should I ditch the one I have an get a couple of polys ? Being an army brat, FMJ is shorthand for ammo and is all I have ever used over .22 cal.

The Polygonal bore was a design feature as it was supposed to use a light Sintered IRON bullet, with would and does eat conventional rifling, and is loaded about 25% hotter than standard mak ammo (if you see a PA 63 with a eaten bore it was probably a package deal with 9x18 vz.82 ammo)

As for accuracy, it is one of the most accurate pistols I have shot, even my brother did well with it. And most of his gun time is programming them in computer games.

If the box in this photo (found on http://en.valka.cz) represents sintered iron ammunition, then I'm certain I put many through an IJ-70 about a decade ago as I recognize the box and may still have some.

I believe the bore on the Russian commercial Mak was chrome-lined and perhaps that saved it from complete ruin, but I probably ran a couple hundred through that Makarov (that I no longer own, so I have no worries).
It's nice to learn new things; I had no idea these weren't typical lead core... I simply presumed they were corrosive and cleaned accordingly.

How common is sintered iron ammo now ? If I bought what 9x18 that commonly available to shoot in my new barreled cz82 will it damage the rifling ? Is this replacement barreled CZ82 a pig in a poke ? The discussion is leading me to think that I have to shoot premium ammo through the non poly barreled 82s.

Everything you're going to find on the net will be fine. Realistically a TON of that 9mm Mak ammo you see is going to be shot through PA-63's, P-64's, and regular old Makarovs, none of which are designed for the oddball "sintered iron" rounds (which you're unlikely to ever encounter). The reality is that the majority of guns out there have conventional rifling and they work just fine.

You should be fine to shoot whatever you want.

The sintered Iron is still made and USED by the Czech Army...
But due to Clinton, it is banned as "armor piercing" Ammunition, and therefore no long importable to the US.

So In the US
I would say it's pretty rare to find a small amount of a relatively obscure caliber, that was imported 15-20 years ago, and NOT SHOT in the said 15-20 years...

HUH
first, I have yet to find any true military surplus 9mak
second, most of it is either made by 'boutique' manufacture like Buffalo Bore or Hornady that manufacture high end defensive loads, OR from MAJOR EUROPEAN MANUFACTURES, who, much like Olin (Winchester, lake city and a few others) also manufacture for their countries defense industry.

Any Ammo in a colored box is fine, if you find a cardboard box like that ^^^^^^^, that says "vz. 82" on it,
and has brass cased BLACK BULLETS That looks like the above, BUY IT
then sell it on the Internet to a guy like me for 2-3x what you paid...
as we would love to have some of the 'real' stuff to go with our gun.
