Another M&P Failure!!!

[chezuki]

What?? Is that a STOVEPIPE in my trusty and flawless M&P Pro?!??

Well, yes it is, but I can hardly blame the gun for this one. My inability to locate any of my powders of choice has forced me to develop a load for what powder I could find. This was from the lightest-loaded group in my gradually increased test batch. It chrono'd at 710 fps... Pretty slow for a 125gr 9mm projectile. It took between 800-850 fps for the slide to cycle reliably, but I worked the loads up to 1050-1100 fps for solid minor PF.

Now the M&P can continue to be flawless and I have one less component to worry about for a while.

Looks like like an 'M&P Failure' failure.

While viewing pic prior to reading explanation, I suspected photoshop.

...when a 230 gr .45 is pushing higher velocities than your 9mm, you can probably assume you're doing it wrong haha.

Best of luck finding a solid load with the powders you have to work with!

Go on Hodgdon's web site and they will have great loads that you will need What powder are you needing?

125gr @ 710fps? Definitely a load fail

125gr @ 710fps? Definitely a load fail

Put those 125 grainers in a sling shot....it would at least be a little faster!!!

Wow did the bullet make it out of the barrel??

If you ever call for steel calibration, I will point and laugh.

It was a starting point!!! I'm making PF now.

Been doing a lot of research into my next handgun purchase and a M&P 9mm is at the top of the list... saw this thread... heart sank... eyes teared up... read the thread... feel much better now...

Anyone got a Kleenex?

Funny stuff.

So what's the load data?

 

[chezuki]

So what's the load data?

The 710 fps was:

125gr LRN and 3.6gr of 7625 with an OAL of 1.15

I worked it up to 4.4gr and I'm quite happy with the load at 1050-1100 fps.

I've been wanting to try out 7625 as cheaper alternative to my beloved N320. What do your SD's look like?

I'm not sure yet. I've loaded up a larger test batch that I'll be sending through the chrono this afternoon.

Im running 7625 - 4.8 gr @ 1.150 with 115 gr plated in my m&p

No chrono for me though
