Hey guys, i am new to the forum. Thanks for your help in advance. My wife and i went shooting today at the firing range. We bought some cheap ammo (tulammo) from walmart. We usually buy federal, but as no one can keep it on the shelf, tulammo is all i could find. Big mistake, apparently, because this ammo jammed both my bersa thunder ultra compact and my smith and wesson m&p 9mm. I have never had the m&p jam on me. After every trip to the range, we clean and and lubricate it. I just got the Bersa not too long ago and this is the first time that the gun has been fired. The Bersa was cleaned and lubricated yesterday before we shot it. After around 50 shots through each one, we ran into a problem. Both guns jammed. I cant clear the round out of the M&P. I can't cock it but maybe a couple millimeters. I have tried looking it up on google and youtube; i can't find anyone else that has had this problem with any gun. As for the Bersa, i got it taken apart and finally got the bullet out and the primer is gone, but the bullet was not fired. After looking at the rounds that are left in the pack, some of the primers are dented in already. I am not sure if this matters or not. If anyone has had this problem or knows how to clear the round, then i would really appreciate your help.
