it is stamped 1946 i read that its not to dependable. what do you guys think?
I shot a bunch of the Turk 8x57 a few years back and it all went bang. I still have a can of it, but don't remember the year made. Very corrosive, so get your corrosive cleaning equipment ready.
63 years old, yep, better wash the barrel down with coffee before you head home to really clean her!
1. Get ready to clean the bore, chamber, and bolt face. Corrosive but reliable.
2. Get the BIG bottle of aspirin- stuff is loaded hot. It WILL hurt the next day.
I shoot 1949 Turk. I bought 2 cases at estate sales. No one else new what it was since it says 7.9 Ankara. $100.00 for 1600 rounds per case. Really decent ammo. It all goes bang and is fairly accurate. It is hot! All I do is run some boiling water down the bore and through the bolt and clean as usual. Corrosive ammo is no big deal, as long as you clean the same day.
so i shot a few of these rounds the other day and you guys were right they pack a punch ... my girlfriend even asked me if the rounds i shot were different than the other 8mm cause the sound was so much more powerful. anyways my question now is about pressure signs... im very new to guns so bear with me.... i noticed that after the first round the shell didnt eject it was stuck to the bolt face... and after every subsequent shot i found the bolt was sticking.... on a earlier thread i was asking how to clean my bolt cause i thought the bolt on my yugo was tough to operate to begin with (i later was told by the gunsmith that it seemed smooth to him go figure) but now im more concerned about the bolt.... if i continue to use this turk ammo will i damage my bolt????
Pressure signs. Look at the fired case, especially the primer. High pressure will flatten the primer so it no longer has the rounded edges. Very high pressure will cause cratering of the primer around the firing pin indentation. You will see raised metal around the indentation. Combine this with an oversize firing pin hole in the bolt face and you will get primer flow. The primer material will become almost liquid under pressure and flow into the area between the bolt face and the firing pin. This can "lock up" the action.
The firing pin hole can be welded up and redrilled if needed. The firing pin may be eroded from corrosive ammo. A new FP may be the cheapest fix.
Yes the Turk ammo is hot. I found it to be reasonably accurate, but not match grade.
What rifle are you shooting it out of?
Just a thought,is the ammo lacquered steel cased?
This sounds an awfull lot like the sticky bolt synrome the Mosin Nagant gets when shooting some milsurp ammos.
Not sure about the surplus stuff, but I've got four 20 rd. packs of non-corrosive 8mm Mauser ammo for sale if you're interested.
Turk 8x57 is brass case. The issue more than likely is if the rifle is a Turkish Ankara it could be a 1893 or 95 action. The sticky bolt is a sign of pressure in Mauser actions. He may have some hardened cosmoline in the chamber also.
+1 on brass cases. I have never seen steel cased Turk 8mm. vmonty said Yugo Mauser. Also said case stuck to bolt face. That sounds like primer flow. Hard to open could also be primer flow in addition to very high presure, dirty chamber or out of spec chamber.
Sorry I missed the fact it was a Yugo. Primers and chamber are possibilities. I wonder if his pin is corroded and is "sharp". How are the forward bolt lugs. Any crude were they lock up in the breach?
Gotcha, Thats why I love this forum,I 'm learning stuff all the time.
You guys are saying that hot ammo in a Mauser can cause ejection problems?
A few more questions, comments.
Does the rifle have an after market trigger?
Is the cocking piece screwed in all the way?
Take a black marker and color the forward locking lugs. Slowly put the bolt in the rifle and put it into battery. remove it and see how much engauged the recess. Also check again and make sure you don't have crude build up in the recesses.
Edit: pics would help
i wish i looked at the lugs more closely before i cleaned them ... and i got to get in my girls trunk to look at the primers on the spent shells ...will report back
when coloring the lugs ... what do i loo at to determine this... how much black is wiped off??
That's a lot of junk to be putting in your girl's trunk. Sorry but I couldn't resist
Classic!! Well done.
Yes you look for what is worn off.
