so i got a brand new zastava m85 7.62X39.

roughly 25% of the rounds i put in it dont go off (even though the primers are hit). this is with ammo that i have gone 1000+ rounds in my sks without a single issue.

also the action gets stiff AF and one occasion required a hammer to open it after firing.

at home the bolt moves around the action fine, so maybe it was overheating?

the failures to fire did occur when the gun was cool.

any thoughts?
 
Where did you buy it? Canada Ammo has helped some of their customers with ignition issues..... I believe it was the spring that was changed.
The stiff action sounds a bit more serious.

I just ordered one from Canada Ammo mostly based on the fact that they will stand behind their products and either fix or replace it if it's not running correctly.

They sell them as a package with surplus ammo and these guns being made in Serbia should be fully capable of digesting surplus with no problems.

yes, canada ammo
 
not sure what the ammo was.

i was told by a respected shooter at the range it looks like the gun has a headspace problem. thoughts?

also i was told that running "hardball" (milsurp fmj?) ammo will ruin my barrel . thoughts?
 
I'd say the rifle isn't designed for a steady diet of lacquered steel case or surplus ammo. It's really a hunting rifle designed for commercial spec brass cased ammo. Lacquered cases will start gumming up the chamber, which is tighter then you will find in milsurp guns. Surplus ammo can be out of spec compared to commercial specs.
Copper washed steel surplus or new commercial production will likely be fine. Same with the zinc/poly coated commercial ammo.
You won't wear your bore or chamber faster shooting steel case ammo, or bi-metal jacket bullets.

I believe canammo sources them from CZ USA, hence the cheaper cost compared to those that Corwin was bringing in direct from europe. I also believe the european ones have been upgraded to shoot surplus.

Maybe a different spring and stock but other then that I can't imagine Zastava changes much for export.

Yes, please email us

One thing I will point out is that we do not currently sell any surplus. All is new production.

Thanks, I thought it was surplus.
What's your opinion on the Zastava's and Surplus ammo based on what you've seen so far?

One thing to note is serbia on produces brass cased ammo. That said, we have only had a few reports of FTF. Mine shoots anything I put in it. Just make sure the moving parts in the firing pin/striker or dry and not full of heavy oil, especially if the weather is cold.

If the respected shooter is a gunsmith then I might believe it's a headspace problem. More than likely it's a chamber issue.
Milsurp will only ruin your barrel if it's corrosive and you don't clean it properly.
Light firing pin strikes are caused by a gummed up, dirty or weak spring.
Send it back to CanAm. He's a good guy. :)
 
I've just posted about the same sort of problems that a friend is having with his Canada Ammo M85 and Norinco ammo. I'll tell him to get ahold of Canada ammo.
 
Sounds like a pressure issue. Make sure the chamber is dry before firing. If it's wet the case will not hug the chamber walls thus putting all the stress on the bolt. If it's still tight on a dry chamber, send it back! I had this same thing happen with a Sako 300wsm. Of course, dealing with Stoeger Canada was a whole other nightmare story.
 
Any time I had to force a bolt open, it was a high pressure load. Check for machine marks on the primer which would also be very flattened by the pressure after firing.
