Well, I took this stuff to the range yesterday, and am going to have to give it a

.
I put around 150 rounds through my Marlin 60 and my Walther P22 and only had 3 failures to fire, which seems to be about the best you're going to get in .22LR without going to CCI mini-mags or the like. UNLIKE the Remington Golden Bullet garbage, those failed rounds all fired when struck a second time. All of the failures were in my Marlin 60, which has a wider pin face than the P22, so doesn't bite as sharply/deeply as the P22. I fired some Federal blue box stuff and compared spent cases from both the P22 and the 60, and noticed that the new Winchester cases don't take as much of a bite from the firing pin. I speculate that this is because the Winchester cases are harder or have thicker brass at the rim.
Accuracy seemed good enough, and I noticed that when compared to Federal ammo, it was more bluntly-shaped with a larger hollow point. It also seems to be loaded just a tad hotter than the Federal blue box.
From my experience, I would recommend trying out a box and see how it works for you - especially as it's the only easy-to-find .22LR bulk pack right now.
