Come one come all! This should make your day.
Let the dead horse beating begin...lol.
Last week at the range, while running some rounds through various mags, I tried a 10 rd Promag full of low brass, after using the same mag with no failures only a few days prior.... suddenly got an FTF in my normally 100% reliable shotgun. Pulled the bolt back to inspect the prob. Shells not even trying to come up to the top in the mag. Hmmm, not the usual problem binding because they fell right out with mag removed and turned upside down.
Removed floor plate and no spring pressure still, even
