CZ barrels

[coebam]

Hey folks,

Curious if the CZ 75 barrel has traditional rifling(1911 style) or if the barrel is polygonal rifled. Considering getting into casting my own bullets. I have multiple 1911's, a G19, and a HK P30. The last two mentioned are poly barrels I run jacketed rounds through. I have been eye balling the CZ75B in .40 and though I could make .45 and .40 bullets if the CZ barrel would work.

Thanks for the input....

The ONLY CZ barresl that are polygonal are in the 9x18 barrels for the CZ-82 and CZ-83. (I'm not sure about the .40 CZ-100, which is still floating around, but no longer being made.)

The rest have conventional lands and grooves.

Traditional. The CZ 100 in 40 I had also had traditional rifling, which didn't help it one bit.

LOL...

Only somone who has owned a CZ-100 could really appreciate that comment.

I dry fired a CZ 100 at a gun store many years ago. I kindly gave it back to the salesman, and tried to flush the memory from my mind, and was successful until this very thread.

Yeap. Great concept, horrible execution. I am certain that the CZ-100 exhibit in the CZ museum is behind a pillar in a corner...only CZ firearm I would gently refuse to own again.

Other than the 82/83, the only CZ derivative I know of that has polygonal rifling are the Jericho/Baby Eagles.

And if you cast your bullets hard enough, and are vigilant about cleaning them and not running jacketed rounds after a session of bare lead, you typically won't have any problems with poly rifling.

Still the simplest way to avoid problems is to just stick to jacketed bullets, KISS is always a good principle to follow.

The CZ-75 in .40 S&W is conventionally rifled and mine does well with hard cast SWCs. Most accurate pistol in .40 S&W imho.
