I don't agree with Mike on the turkish ammo. I have seen and repaired some remarkable blowups in a variety of guns that were not related to the barrel but to the ammo itself. Its a lottery with that stuff. Some guys have fired tens of thousands of rounds and had no issues but many many others have run that ammo to their woe. We ran some chrono tests on it and found velocity varying from 1900 to 3600 fps. I don't believe the ammo is as the bolt action guys claim....Hot. I think its just been stored badly and some is ok while some rounds are really really bad. Same goes for the indian 308. Too many occurences of damage to make it just an oddball thing. One blowup might be the guns fault, 2 might be just the odd bad round 100s of blowups tell me its definitely ammo related. Between all the smiths and MG mechanics we find that there was an inordinate number of guns damaged by the turk stuff so Mike is welcome to all there is out there. I only bought a few thousand rounds to start with and it didn't work in my guns. Lots of sticky chambers, failures to eject, extract and such. Customers brought in guns that were damaged though and I dumped all the ammo I had left to the bolt action guys.
On the other hand I believe the yugo issues were entirely barrel and chamber throat related. The only guns I ever saw issues with using the Yugo 50s dated 8mm were the brownings which tended to blow topcovers and the maxims which didn't have enough oomph in the firing pin to fire it reliably. Hard primers that were deep seated cause issues with them. I never saw a gun destroyed with this ammo and never really saw any damage beyond the bent topcovers. I've run it in MG42's, MG15's, MG81s, some maxims with strong firing pin springs, 1919's using barrels I made with proper chamber throats. For some this ammo has been tainted by the internet gurus who claim its bad but most of us who actually shoot MG's its good stuff. The 70s dated stuff is prettier and seems to have less issues with the deep seated primers. I like it all.
Having said all that I'll also state that the romanian 8mm is some of the best surplus that has come in to the US. It is reliable and works with pretty much every gun I've ever fired it in. I have no idea if its got moa accuracy and I don't really care. It runs the guns even with its very light for 8mm 150gr bullets. It is a little sooty but what the hell, its machineguns we're shooting. They need to be cleaned. The bolt gun guys whine about cleaning corrosive ammo residue after shooting as much as 50rds in one sitting. We tend to shoot thousands at one sitting and cleaning is a must. So my opinion is that if you can get your hands on the Romanian buy it. If you can't than buy the Yugo. Don't buy turk even if its given to you. Have them send it to Mike.
Just my thoughts base on the experience I've had with the stuff.
