This is not a slam but I recently had a bad day at the range using the Federal Punch 22LR ammo. I took all my Mouse guns to the range for ammo evaluation. All firearms were clean, properly lubed and are in 100% operating condition and have been 100% reliable in the past. I loaded each one up with the ammo. I had a Beretta 21A, S&W 61-3, S&W 2213, Walther TPH. I fired 15 rds thru the Beretta without a problem, then it fired and failed to extract the empty brass. The brass was swelled up in the chamber and I had to tap it out with a squib rod. It did the same thing with my S&W 61-3 and 2213 as well as my TPH. I attributed the fault of the ammo. Could it be developing excess pressure? I finished the range session using CCI Stinger ammo and every firearm worked perfectly without any problems. I fired a total of 20 rds of the Federal ammo in 4 different firearms and it failed to extract 5 times. I have either got a bad lot or something else is going on to fail to extract in 4 different previous reliable firearms? I purchased the ammo direct from Federal and have the fired case that was stuck in my Beretta 21 which I had to take home to tap it out it was so stuck.
