Valmet M76 - First "Stovepipe" Jam Ever

Post by GoodGuy » Fri Nov 04, 2005 5:13 am

I had a tough day at work yesterday, so I went home early and thought I'd blow away a little ammo to relax. I pulled out my trusty M76 and a hundred rounds of Yugo M67 and started blasting away. For the first time ever, I experienced a classic "stovepipe" type jam. I stopped shooting and examined the rifle It was clean. The gas cylinder, piston, gas hole, chamber, bolt carrier, etc. were free of any fouling or obstructions. The Valmet factory magazine I was using has been historically reliable. The cartridge casing looked clean and smooth. No issues with the ejector or extractor. Bottom line... no obvious issues with the rifle or cartridge casing. I suspect there must have been an irregularity in the load resulting in a pressue issue which, in turn, caused a short stroke.

I continued shooting without any other reliability issues. I guess even Valmets can have a jam now and then.

YUGO ammo could be the problem

I have read a lot of bad things over the last 2-3 months about yugo ammo.
My ammo guy stopped selling it in both 7.62x39 and 223. I thingk I just read a thread about a Century CETME goung BOOM with some Yugo. But, who knows if the bolt face was ground like several that I have seen.
I could be wrong.
I just need a 76 milled folder in 7.62 x 39. and I swear to GOD I will stop.

:shock: Interesting. I only have about 900 rounds of the Yugo remaining in my stash. I think I'll suspend firing it in my Valmets and use in in an old SKS instead.

Check your extractor for wear. I have had this happen on other weapons and found a weak extractor spring or worn extractor. Could be the Yugo ammo as well.

This is most likely an under loaded round. I have had a few of these back when I used some Wolf .223. Try some different ammo and see how it works.

Use quality ammo and you don't get jams and stove pipes.
Surplus ammo is for cheaper guns like AK-47 not for Valmets and Sakos.
