M305 and Tula ammo kaboom

Got the case out with some magyvering using an eye bolt and some rope and lots of yanking. I already have an forster .308 field guage (1.638") and a 7.62 max guage (1.6455"). The pictures below show how the bolt closes completely on the 308 field guage but doesn't quite close on the 7.62 max guage. I saw some things online that says this is ok but to me if it comes that close to closing without being forced I would think itncould possibly be dangerous to fire?

Some brands of ammo can take a bit more then others with loose headspacing, federal for sure can't

but Like I said, some norcs the head spaces moves with very few rounds fired, the components start to "peen out" a bit. It doesn't take much.
 
I don't see headspace as causing this

looks like simple OOBD

Do you have any other cases from the same shooting session that show signs of head seperation ?

How does one go about finding a usgi bolt? EE or can they be ordered somewhere?

you'll see them on the ee or sometimes I run guns can get you 1-the best are trw , but you'll still need someone to lap it in

unfortunately there's a lot of smiths out there that say I DON'T WORK ON NORINCO JUNK" - all you have to do is find one that is- 45 acp king is out of the business, but barney ( tactical teacher, hungry) is still around and he's forgotten more than us will ever know about the m14 platform
 
when I bring the 3 kings back on line i'll be in the same boat as you- trw, springfield, and an h&r but they'll have AMERICAN made receivers - to tell the truth almost any smith that can work a garand can workon the m14 platform- it's just pride

the case was jammed in the chamber and the head was blown off. if it was an out of battery unsuporter lugs the case should have split no? it would have had to been partialy locked in to get the OP's result... and it would have likely sheered the bolt. this is very similar to when mine had a head space issue and the case head partially separated... big poof in the face, but no pieces flying off.
 
The other ejected cases looked ok at first glance aside from the one where the primer looked to have almost blown out. I didn't look at them all however, only 3 or 4

Are you guys sure it wasn't bad ammo? I remember reading about bad Tula ammo a week or two ago

^^^This!!^^^.....i have a Norc "M14"...thousands of rounds of various types down the pipe with never an issue...I bought 1000 rounds of this same Tula Ammo about a year ago....have ran less then 100 through my rifle and this has happened twice now. No reason to post pic's as they would be exactly the same!! Tula said they have never heard of it, gave me some loose answer of providing a visa cc recipt to prove where and when I bought it....over a year ago...life has got in the way and it's just became a waste of money and a "lesson learned"....anybody want to buy some (900+) 7.62x.51 Tula ammo?
 
I should mention again that before it happened the rounds I did fire definitely felt more violent than usual. The recoil was more and it felt like the bolt was coming back harder than normal. I think it was mainly an ammo issue but I'm. Just curious as to whether my norc is still safe to fire with better ammo
 
I also still have more Barnaul and MFS ammo left over. I've always has good luck with mfs but now I'm wondering if all this Russian steel ammo is basically the same
 
in all my years of running the 14 I've NEVER RAN STEEL CASE through it- any of them -nd one of my cohorts said it might be worthwhile to clean YOUR FIRING PIN HOLE- there might be debris in there that's not allowing to the firing pin to fully retract- I've had a similar incident to yours but it was too many reloadings( Winchester) in a real 14 ( springfield )and not the following the 4 and out rule- I think it was 5- complete head separation - split the stock, fragmented the mag- tube split, spring went boing, and follower recovered - all we needed was a new tube and stock
as an aside, the guys that used to run the m105 howitzers ran into nothing but trouble when they used steel cases- sticking, jams whathave you- switched to brass casings and problems disappeared- something about the coefficient of steel/steel and the coefficient of brass vs steel and these were American arty men- that was enough for me

get out your bullet puller, get a good load(weigh your bullets) and put it in brass- use the powder for fertilizer, pop the primers, and crush the cases
 
The basic physical properties of steel vs brass and the fact that your bolt nearly closes on a 7.62 max guage while using steel cased .308 and this isn't so surprising. With less headspace the tulammo might fare better. Norc 7.62 does awesome in these rifles, tulammo blows sh!t up. But lets blame norinco.
 
it really bugs me how people buy a gun, even a reputedly cheap gun and then insist on running chit ammo through it- the fist question out of your mouth should be is it steel cased and the second should be is it berdan primed- and where's it from- there's some indian 7.62 I wouldn't touch with a 10 foot pole- b/c is is KNOWN to turn your rifle into a grenade- if you can't afford brass and or dies to make handloads, you SHOULDN'T BE IN THIS GAME
even my old no 4 never saw a round of berdan- and that was back in 1970, when such things were plentiful - first thing I did was buy a partner press , scales, and a lee loader- the 10 dollar tower hammer the chit out of it - there's entirely too much of this I wanna make it go boom now to suit me
 
b/c they're completely useless- even in brass form- most normal folks can't reload them and the world would be better off without them

ever consider that in the places of the world that use them... they might not want "the people" reloading them?

let me ask you this- do you police your berdan primed brass or do you leave it like the rest of the slobs that use it-part of the reason boxers are used is that you can 3-4 times out of a case not so with berdan-
