Hi, I’ve had my PS90 for about 5 years and run roughly 2,000 rounds through it without a single issue…until my last two trips to the range. I was firing SS197SR ammo (Product #: 10700017) and had several failures to feed some rounds simply weren’t stripped from the magazine and moved to chamber. Simply pulling the charging handle seemed to remedy this. There were, however several rounds that became lodged between the chamber and bolt assembly and some that were positioned at an angle with the tip in the chamber and the bolt closed on the other end. I was using a factory 10-round magazine that I have used for quite some time with no issues.

The next week I returned to the range with a clean factory 50 round magazine and proceeded to encounter jams of the same kind. Once again, I was using factory SS197SR ammunition. In one instance a case became lodged in the chamber and the primer had been pulled out and crushed.

I find it odd that this would suddenly be happening. I clean and Lube the weapon after every range session. Does anybody have any suggestions or perhaps have a contact number for a helpful customer service rep from FN?

Thanks in advance

Popped primers are not uncommon in this caliber especially even factory rounds. I see what looks like only a partial primer crimp in the 7-9oclock position. Have you ever used a 9mm or 40 cal brass/bronze brush and carb cleaner (not brake cleaner or other conventional gun cleaners) to clean the chamber? Brass coating does and will build up in chamber

While I've read how horrible the AE is (I've fired some rds and have been happy with them), I see just as many threads like this one demonstrating SS197 FTEs and FTFs. My personal gun/rifle troubleshooting starts with the process of elimination to identify the failure point. I would start with different ammo and lots #s, mag (consider the man kave delrin mag pins http://fnforum.net/forums/fn-ps90-accessories-mods/49362-new-product-man-kave-p90-ps90-mag-pins.html), rifle internals (clean and clear) and then when all else fails, send the rifle to FNH. Just my opinion :icon_angel:

I have seen 2 popped primer issues in about 200 rounds of SS197 in my PS90 in the last couple of weeks. In both instances, once the primer was struck the bullet fired but the felt recoil was "different" and I knew something was amiss. The spent case was not properly ejected.

I had pre-loaded my magazines and so I didn't have the boxes I could go back to in order to record the lot numbers of the particular ammo. I am guessing there may be some quality control issues with certain lots of ammo.

Willing to take all the junk AE ammo any one can muster.

PM me with details and see if we can work a deal.
I wonder if this is newer lot#s doing this?
i will also take the " junk AE " ammo ...

The newer lots question is a good one. Unfortunatley I have been shooting surp from my stockpile and mostly AE.

JIMO:

I have posted this the other day however... what I have found specially with AE or any SS round that comes misfed, if the bullet gets pushed back into the casing and the powder contaminates the internals of the weapon.... might as well STOP SHOOTING and take the weapon home for an extensive cleaning.

I had a terrible day a few days ago, was out at the range, with a dirty gun, gave it to my brother .... and after a few rounds the AE misfed, dumped powder all over the internals ( because we cleared it and continued shooting ) it happened again & again, my brother finally ripped of my ECH ????? and I just about wigged out.
I have never seen that happen, but the powder in the internals was the root cause, the gun required an extensive cleaning.
These weapons do not like dirt, let alone excessive powder. I'll will tell you it was a real mess.

just my .02
