This is a better comparison.
As you can see the primers are more flattened on the top ones.
Especially on the one on top, in the lower left.
ALL firing pins REBOUND and that will NOT cause the primer to be more flattened. That is PRESSURE.
Pressure is equil in all directions, and the firing pin is the only differance in restriction.
The flattening is past the firing pin dent.
If tha one primer I mentioned was any flatter at the edge of the radius, I would say you were getting into a high pressire situation.
But why, from the same gun, are there so much differance or variations in the look of the primers.

Good discussion.
It would be difficult to draw correct conclusions by comparing cases from different lots fired with two different handguns. The point of discussion here is first pic which shows two rounds of same lot fired from same gun; one fired and one didn't. I see a difference in firing pin mark, even after giving allowance for back pressure in the fired round. The two strikes do not seem to be of equal strength. But its not conclusive and needs to be confirmed.

MR, can you try the misfired round second time and if it fires, lets see how the pic looks like. :)

Yes KBW, good discussion ... it has gone too much wayward, thanks for bringing us back to the initial point.

Also, will try the round again and get back!

Update:

I did try the dud three times again, but it didn't go off.

Also, I tried the same ammo with a different handgun also, a Sarsilmaz B6, but the result was the same. Fired 40 more rounds from two different handguns and got 8 more duds! So my initial report of 20% failure rate remains correct after a total of 45 rounds fired!

Image
These are all the duds!
The left most bullet is the previous one, shown in above post. (It was tried 3 times in CF98 after that!)

20% failure rate?
I wouldn't even buy that for casual plinking.
All the stoppages would just take the FUN out of shooting.

It is also NOT a good cantidate for salvaging the cases, only the powder and primers.
But trying to tear apart the ammo , especially the Duds, might be of help to identify the cause of the failures.

You know I'm gonna do that LAGS!!! ;)

Why not a good candidate for salvaging the cases??? Also, I don't think salvaging the primers will be a good idea! :?

When I said to not salvage the cases, I meant the PRIMED CASES for reloading with different powder and bullets.
But there is nothing wrong with the case itself.
But until you clarify the problem, I wouldnt trust the Primers.

Latest Update:

I did try the rest of the rounds, when a friend came by with his Glock17!

While the failure rate of this ammo in my CF98 was around 20%, it was more than 50% in the Glock17! :o
Image
These are all duds, the left ones (mostly) were shot (tried, that is) in the Glock17 and the left ones by the CF98.
Total 25 failures out of 100!

If you closely look at the carts tried on a Glock17, the firing pin strike seems very shallow or light! Is it due to the striker fire tech? do they strike lightly?

Because if that is the case, a Glock17 claiming to be an eat-it-all, is not so true! Specially in the case of old hard primer mil ammo! :think:

The Chinese CF98 and Turkish Sarsilmaz performed comparatively well in relation to the Glock17! :D

Comments?!?!

@ MR
if you could, pull apart the duds and try to identify why the FTF.
Was it bad primers, or bad powder.
