Her Mossberg 715t Flat top is a Dirty Harlot

So we made it to the range for the first time since it came back. Still jammed like crazy with the ejecting brass getting hung up over top of the chambering round preventing it from achieving battery by the diameter of the brass , so i ran a test.

I took 2 magazines and wrapped them with electrical tape just above where the metal meets the plastic, just enough so they do not rattle. I ran 2 full magazines each 555 and blazers one taped and one without tape.

Blazers in the taped mag worked 100%, in the non taped mag every 3rd to 4th round did the super jam.
555 in the taped mag would stovepipe occasionally, in the non taped mag every 3rd to 4th did the super jam.

I also ran a non taped magazine of each mini mag and thunderbolts did not seem to matter still super jammed every 3rd to 4th round.

In conclusion i stopped using the non taped mags and the failure rate went way down, to a point where it was enjoyable. I would get the occasional stove pipe nothing a simple pull on the bolt would would not fix. It was just to bad i forgot to pack the loader.

I am going to tape up the other 3 mags to confirm my results.
 
Thanks for the info. Mine was doing the same as you described with the 2 original mags I had. I bought 4 new ones and haven't had anymore problems. I will have to try the tape on the 2 original mags. I hope it works for me as well.

What's the easiest way to get the lead out of the muzzle break?

Heat gun or a butane lighter and a small flathead jewelers screwdriver
 
In a rimfire semi-auto, you really should run a new synthetic CLP type product. It lubes the action, keeps carbon from baking on, and prevents fouling buildup, which you WILL get if you run it dry. And if the lube starts looking terrifically filthy while you're halfway done at the range? Spray more lube into the action - it'll keep cleaning it out while you shoot. And it won't hurt your synthetic stock.
 
I just did a complete teardown of the entire gun, including the trigger assembly. First time since I bought it from new about 8 months ago. Man was it dirty, tons of debris stuck everywhere in the original lube. I cleaned it all up Froglubed the crap out of everything and reassembled it. I also took the 25 round mags apart did some trimming on the sharp edges, as the other poster suggested and wiped them with Froglube too. Let's hope this helps with the FTE problems I've been having as well.
