CCI/RIA. Not playing well together

[JustEd]

Rock Island Armory 10mm 1911.

My friend has exactly the same RIA 1911 as I do  Have seen him shoot a couple hundred rounds of PMC and Magtech 180gr ammo with no problems

On my advice, due to 19.95 per 50 round box price he purchased Blazer 180 gr as shown.  In a single ¾ box he had four primer blowouts   This is his pic so don’t have more to show  

I checked his 1911 and it does not seem to allow firing out of battery  There are no signs of hard primer strikes or case bulging  The weapon cycles great with other ammo

So this is mostly a heads up for 10mm shooters looking for a bargain   Sometimes you get what you pay for

Also, I tried 8 rounds of that Blazer box out of my RIA 1911 but had no problems  Spent cases on either weapon look normal, except for obvious primer blowouts outs  Most had normal primer strikes  Again, no case bulging. Also cycled live ammo through chambering and extraction cycle without firing and cases looked normal.   

I told him to contact cci/blazer before sending his 1911 in to RIA

 

 

This only shows 3 rounds  Fourth had identical blow out to top center case

Again, just a buyer beware heads up

Correction on bullet weight

Posted here rather than ammo as it is possible the gun is at fault. Just can’t see how

Look for a small burr on firing pin nose... Rub your finger over it n look at it with a magnifying glass if ya can .

NO BURS

I have experienced CCI Blazer ammo having primers back out under strong recoil.  That was on aluminum case ammo in 45 and 357.  Wonder if that is happening in the magazine as the weapon cycles then a round with a poorly seated primer gets chambered and fails ???

Interesting...

It well could be... The aluminum cases may not hold the primer as well as brass does..

Asked for a photo of the round with primer looking sideways as Garufa noted. He did not still have the round but noted it looked more like gas had escaped around the sides of the primer in two spots leaving a carbon trail

That sounds consistent with the blow outs

typo

I honestly think it’s just a bad batch of ammo.  It happens, but Blazer Brass is generally good stuff.  CCI should be contacted.
