james, I was a bit hesitant to respond to this, I made the first caliber conversions for the brownings and sold a few starting in the late 60's. I can tell you for a fact that all the blown guns I or associates examined were due to faulty barrels and so called experts giving wrong headspace directions. this worked out to my advantage as the big boys like J+G in Prescott az and others stopped selling the turk and other lots of 8mm. in turn I purchased just short of 1 mill rnds for less than .04 AND THIS WAS IN THE LATE 90'S.
I still shoot the turk 8mm / 50's Yugo in ALL my brngs. I have never blown a case, but HAVE lost some primers to be honest. no way to track it but a lot of the Yugo 8mm was made for the brngs. see they had all of our guns that the germans captured early in the African campaign along with MANY OTHERS. on a buying trip I managed to include a large quantity still in links dating 48/49 again never a problem. the older Yugo ammo will have VERY hard primers which limits were it can be used and adding to the bad reputation. another issue that surfaced at the same time as blown top covers, was covers coming open while running which meant a broken extractor PLUS. this was due to improper builds,IE the topcover latch clearance. NO I WOULD NOT SUGGEST YOU RUN OUT AND BUY TURK 8MM, save it for me. but I would not hesitate to run ANY Yugo 8mm in your brng. the way to play that is choose a vendor, get a small amount, test it the respond accordingly. it should be less than 1/2 the price of the new stuff and well worth it. the sad part of this is we have had no control over its storage since imported exposure will be a big issue. I keep ALL my ammo in climate controlled storage and have done so the last 45 years. I still have a large quant of WWII brass german I use in my 34/42 . last summer I noticed we were shooting 1918 dated FA 30/06 in a couple belts??? as long as the headspace is right with a proper chamber , the worse thing you can expect , is a mis fire or no cycle
THE AMMO TO BE WORRIED ABOUT IS ANYTHING FROM SOUTH AMERICA!!!! can you say BOOBY TRAP? I witnessed a Canadian bren explosion and picked up a sample from the can. found it to be stuffed full of pistol powder!. an argentine colonel related to me that they indeed planted booby trapped ammo for the insurgents to liberate , that's all it took to convince me. shooting and contributing to others shooting, was the sole motivation for me to market the caliber conversions. when I became disabled and unable to meet my commitments, I turned the whole operation over to troy at barrel exchange who has done FAR BETTER THAN I to keep these things running. its been fun the only limit to the brong system was links but I did run 38spl/.357, .410, 6.5 dutch,7x47, 7x57, 8x57 30/30 7.62x39, 5.45x39 7.62x54 as time passes options will vanish. with all the ammo I have on hand, I still scrounge small lots at the show's for components and suggest you do the same while you can. I see 9 round belts in the near future any way so we might be limited to looking at best... cheers mike ps, if you have failure to fire in your 17, relieve the face of the fire pin to increase protrusion. go slow a little at a time to avoid punctures. this has worked well for me with some lots
