Soo my Type 97 just blew up on me

That is the headspace clearance, very normal looking too me. Also an out of battery fire would not destroy the bolt like that as the pressure can escape. Now a high pressure with a locked bolt... well you can see it from the photo.

That's how i feel about mine, I'm not worried at all.

Really more impressed than anything.


And I've ran mine with tons of commercial / soft primer ammo. No issues, but it's a free floated pin, all the booms were on a trigger pull, and not a bolt slamming home.. Weren't they?

Just a personal experience from last week.

Friend of mine show up at the range with his T97.

I was zeroing my CC C7 with some reloads I had. Nothing to worry there. None of my loads are HOT and after thousands all of them ran perfectly in all my AR type rifles. 24g of ramtac. 62g FMJ-BT with cannelure. IVI brass. usually around 2850fps

So first I give him a box of factory ammo ( 20 american eagle 55g ) I had. Shot it with no issues at all. Tried myself and all went good.

After a second box. I wanted to try my reloads. All in specs. But....

We both experienced something unusual.... When releasing the bolt forward, the tip of the bullet was getting caught on, I have to say, the very square "feed ramp". Well feed ramps are almost non existent but you guys can picture it I am sure. So we got 3 rounds where the bullet got pushed inside the brass partially... Not good.

I do not crimp my 556 reloads. Looks like that particular rifle do not feed the rounds smoothly and it can cause the bullet to be pushed partially inside the brass and could dramatically increase the pressure. All factory crimped rounds where ok.

One of them the bullet went all the way inside the brass and created a powder spill all over his chamber.

That was the end for that rifle that day.

:confused:

Known issue, if there is no problem with crimped rounds... Just use crimped rounds...
 
Glad to hear you are all right OP, It takes a big man to admit his mistake- and we ALL make mistakes!

I had a bullet pushed back into the brass this weekend on my AR, factory rem .223. I was using LAR mags and the tip seems to get hung up on the front of the mag, I could see where the rounds had been dragging over it but only one caught bad enough to drive the bullet back and cause a jam. Pmags were working fine though.

Might file the front of the lar mags down some as I would not want a round to get compressed and then find it's way into the chamber without me knowing.



Here's a crazy thought and there are probably a myriad of reasons why it would not work but could the powder manufacturers add a coloring to powders so you would pick up on a wrong powder easier?

Like Red Dot and Green dot powder.
Yes, it has been done, but with over 100 powders, it gets a bit hard to tell the colours...

and people still mistakenly put diesel in their gas cars, you cant always fix stupid :p

well they changed the colour of the fuel caps!

it used to be yellow was diesel
Red/Green/black was gas

Now I see green for diesel, yellow for diesel, black for diesel

And yellow for gas, black for gas, green for gas....

And a lot of vehicles don't actually say what they take anywhere you would think to look when unsure (cap, filler neck area, gas gauge/instrument panel). these little diesel cars sound not much different than gas. Its my worst nightmare when driving a rental....
 
Anyone who thinks sticking to factory ammo is the ultimate answer will eventually get an ugly surprise - I've had 2 different brands in 2 different calibres show excess pressure signs - 1 round of UMC 9mm that was over pressure enough to cause a problem with a CZ85 and a round of WWB 223 that blew the primer out. This can happen at any time, and with any brand of ammo and in any gun. Part of the game, unfortunately. I'm glad the OP is OK, anyone feeling superior needs to remember that it only takes a couple of minutes of inattention to cause something like this.
