I've run hundreds of rounds of the stuff through my several 9mm's over the past year and a half without a single problem. When you say jamming are you talking about failure to feed or failure to eject? Also how many rounds do you have through the pistols? Weakening springs can cause failures.
I cant even remember how many round of this I have used in various calibers over the years. Ran it in a number of different guns for plinking and range ammo, never had a moments trouble out of any of it. Kind of stange to here someone not liking it, all my buddies I shoot with use it also. May have just been a bad box or something maybe, were both pistols clean? that could be a problem
I've shot it in a sig, two glocks, and xd with no problems. I love the affordability of shooting a factory load. It's not as cheap as buying Remington UMC in bulk but I find it to be a little cleaner in my guns. It's also in stock every time I go to wal mart.
thanks for the reply's i am shooting a 9mm s&w new, a jimenez, which fires it better and a luger 9mm all guns seem to have feed problems not jams in chamber. i now shoot remingtons,and sellior belloits, and reloads no problem, maybe it was just a bad lot
