I'm Back......
.... with the long overdue ammunition testing of the 2nd replacement(or as in 3rd Walther P22) that was received from S&W/Walther USA on 09-29/03 of last year.
I know this seems like quite a delay(and it is), but as we were in the process of having a new house built, me working for myself(computer systems consulting), two hospital stays for the MIL(we were/are the main contact/support for the in-laws for these situations) and all the other little things that seemed to pile-on during this time frame.... well, the ammo test just wasn't very high on the priority tree during that time. In any event, sorry for the delay.
Now then, here's the ammo test .
Total different manufacturers: 5
Total ammo types across manufacturers lines: 17
Total rounds fired: 1020
Failures to feed: 38
Failures to Extract: 41
Failures to Eject: 4
Jams of any/all Types: 11
Failures to Fire(on first strike): 13
Ammo used:
Winchester Power Point X22LRPP
Winchester T22 Target XT22LR
Winchester SuperX Hollow Point X22LRH
Winchester Wildcat WW22LR
Remington Subsonic Hollow Point SUB22HP
Remington High Vel. Hollow Point 1622
Remington Yellow Jaccket 1722
Remington Viper 1922
Federal American Eagle AE5022
Federal American Eagle AE22
Federal High Vel. Hollow Point 712
Aguila Super Maximum Hollow Point
Aguila Super Maximum Solid
CCI Stinger 0050
CCI MiniMag 0030
CCI MiniMag 0031
60 rounds of each ammo type were fired, 20 rounds through each magazine. The three magazines were two 265 93 44-A and one 265 93 36-A, which are the finger rest and flat bottom magazines, respectively.
The ammo types that experienced no failures or jams are:
All winchester ammunition tested
All Aguila ammunition tested
Remington High Velocity Hollow Point 1622
CCI MiniMag 0030 and 0031
The most troublesome/failure experienced ammunition:
Remington Yellow Jacket 1722 - 20 Failures to Extract, no other types
Remington Viper 1922 - 24; 16 Failures to Extract, 4 Failures to Eject, 4 Failures to Fire(on first strike)
Federal American Eagle AE5022 - 34; 12 Failures to Feed, 12 Failures to Extract, 2 Failures to Eject, 10 Jams of varying types
All magazines experienced failures/jams with the ammo that was not 100% reliable, so it would appear that the f/j's were all of the ammo related variety and not related directly to the magazine in use. That's a good thing.
The barrel used was the short 3.4" barerel, with the barrel nut being prepped before testing, with the use of Loctite #242(blue non-wicking). No barrel nut loosening was experienced either during the test progress or at the end of the testing. No attempt at accuracy testing was performed during this test.
Mechanically, the pistol, with ammo it likes, performed well. However, the safety seems to be a bit on the loose side, with the safety actually dropping to the safe position when the slide was dropped on the first round of anew mag. This occurred 7 different times. Also, some ammo types have a nasty habit of being ejected directly into the shooter's face or the forward portion of the head above the forehead.
A post-test review of mechanical condition will be posted following the post-test cleaning. Stay tuned to this Bat-Channel
