The Wally World Winchester Wonder ammo

After hearing all the talk about the Wally World Winchester Wonder ammo I went out and bought a couiple of boxes. Ran a few over the chronograph, here are the results:

I used five Lugers, two DWM's, two vintage Mausers, and a Mitchell, all with four inch barrels. Mean velocity was 1107.7 fps at 10 feet from the muzzle. Standard deviation divided by velocity among the five pistols averaged 2.88%.

Out of sixty or so rounds, I had one malfunction in a 1938 Mauser. Cartridge stopped half way up the feed ramp, perhaps not quite enough steam to get the breech block all the way back although the hold open worked. On the other hand this same pistol produced the smallest variation in velocity among the five.

I would rate this load as no better than average for consistency, but keep in mind it's an econo load not a premium load. I would rate it as a bit too hot for an old model (flat recoil spring), about right on for a new model DWM and just a bit on the mild side for a vintage Mauser. Assuming factory spec recouil springs.

Meant to run this stuff through my Ruger P89 as a control but left the 9 mm spring at home. Did run some 40 S&W through it with such a light load I had to use the 7.65 mm Parabellum spring.
