Trouble In Paradise . . . With Reloads . . .
So, went to the range yesterday with my mom. There's a separate thread for that.

Just wanted some help. My reloads (9mm) gave some problems. I'm using about 3.8 grains of Bullseye, with a 125 grain lead round nose bullet.

I had a number of failure to ejects out of my S&W M&P9. No other problems, only failure to ejects. When it happened, the slide basically locked to the front, and I would have to grip and pull it pretty hard to be able to knock the case out of the bbl. The bullet would shoot, but then the problem happened. I had to put a rod in the bbl and knock it out with a hammer. This happened several times.

My thoughts on this matter:

1) I'm leaning towards it being an issue with my reloads.
2) Maybe the extractor on the gun is actually starting to have issues?
3) Could it possibly be a magazine issue? I have no idea.

I almost never buy factory rounds for 9mm. There's no point (except for defensive rounds) when I can just reload.

Anyone have any thoughts?

I'd check the extractor for issues and the chamber for burrs. Take a look at the fired casings see if anything stands out.
I'm not a reloader but to me it Sounds like your loads might be a bit hot if you don't find any mechanical issues.
Almost no possibility that it is the mag.

Do the primers look flattened?

Good answer, and so often overlooked. Shall we keep them in suspense until you get an answer?;)

The suspense is killing me Doc, post away :)

also JW, can you drop the loads into your barrel (when the gun is taken apart) and will they slip in easily or are they already a little tight to begin with?

A flattened primer indicates a hot load. Pressure is blowing back through the primer flash hole. A lot of times you will also see a raised edge around the firing pin strike mark.

Take a 9mm case that may have been reloaded a time or two too many, add in a hot load, and you would get exactly the signs described by the OP.

EDIT> By the way Anna, that was a good catch on your part. Many people will fail to look at that, especially in a firearm that ejects it's brass.

May actually be under powered and not fully cycling but still expanding the case in the chamber and binding things up.

That's not a hot load. Not according to my manuals. Neither is it at the bottom end. It's possible but not likely that the cases are too long. Unless you got hold of some 9x21 cases. I'd check the extractor for crud.

Hey JW357 how many rounds since you cleaned that gun? If my gun was locking up like that I would break it down immediately just to make sure there is not some debris stuck between the slide and the frame. Make sure there is not something stuck in the chamber as well. Maybe your reloads...maybe not.
