Ammo compatibility

[mjkten]

This may be just an ammo thing, but I was practicing with my M&P 9 Pro this afternoon and had three failures to feed out of about 150 rounds.

Ammo in question is Freedom Munitions 124 gr HP. 

The rounds had a distinct line across the tip of the bullet, and the bullet appeared to be driven into the case slightly.

Any one else experience this? I've had no issues putting the same bullet through my CZ 75b.

Needless to say, I'll be  buying another couple hundred of some factory round nose for IDPA match this Saturday.

Thanks,

Mike.

What kind of "failure" was it?

[mjkten]

Nose jammed low on the feed ramp. I had just gotten two new mags so i isolated those and replicated the issue with a trusted mag.

Am i mistaken about the source of the failure?

I had this exact same issue with my M&P Pro 9 when I first got it using new Fiocchi 115gr. I attributed it to a bad box of ammo.  Have shot over 1,000 rounds using the same ammo and hasn't happened again.

 

I would guess its the ammo.

For me, a nose in feed ramp jam is almost always a mag issue, usually a weak spring. Sounds like you may have ruled that out.

I guess I need to keep it clean,  lubed and well fed.  But I sure don't want a stoppage on Saturday.  I bought 4 boxes of Winchester NATO 124 gr for the match.  A bit snappier than the FM.

 Although I knew which mags were new,  they're not marked.  (Gotta do that) if I have another issue with different ammo I'll pull that mag out. But the gun is new and I have 8 mags,  all new.
