CZ 527 in 7.62x39 barrel service life
« on: August 25, 2017, 07:53:59 PM »
Dear CZ 527 users,

How many thousand rounds CZ 527 in 7.62x39 can shoot with maximum accuracy?
I am asking about quality of barrel. For example: 308 win can shoot 5000 rounds with good accuracy etc.
Please share to me experience and minds

It really isn't a gun that is designed for maximum accuracy, and neither is the 7.62x39.

It's more of a gun that you can shoot cheap surplus ammo out of with "reasonable enough" accuracy.

As far as barrel life, I think it depends on what loads you are shooting.  Bimetal and plated steel rounds would be the shortest, while cast bullets would be the longest.  Standard cup-and-core lead/copper bullets would give the most "normal" barrel life.

I shoot 200 to 250 rounds a year for load development and shooting feral hogs. I'm setting at 1722 rounds according to my log book, so far no sign of throat erosion or loss of accuracy. I don't expect match grade accuracy. The load I've settled on will group a 123gr Hornady SST consistently about an inch and a half at 100 yards. That's fine for a round I wouldn't push past 125 yards on a game animal and maybe 150 yards on a smaller feral hog or goat.

I never kept any logs with my rifles, (really should have, too lazy), but my CZ 527M has shot thousands of round, factory and handload, jacketed, plated and home cast lead, both powder coated and traditional lubed, and it will still hit what I aim at. :) I've had this rifle the longest of what I own at the moment, and it has always been one of my most fun to shoot. I do shoot mostly cast lead nowadays, and with the powder coating I'd hazard a guess that the bullets are very easy on the bore. I admit to not shooting as much as I used to with some other fun guns to play with, (BREN and Scorpion), but she still gets out for maybe 500-1000 rounds a year.
