Went to go shoot my Walther p22 today and I am trying out all of the different kinds of ammo so today I picked me up some of the Federal AE in the red box. 96 cents per 50. I had about 3 or 4 FTE per magazine. I haven't had any problems like this in the last 1500 rds. through this gun. Has anybody else use them? It would only the Federal that would do this I had some 550 rd value pack left and had no problems.
