Just got back from the range where I did my second round of tests with my relatively new (about 400 rounds) SS Bobcat.
1. MiniMags, which all my other autos love, follow a pattern: First shot cycles partway, leaving the slide about 1/4" shy of closing. I push this with my thumb, and the rest cycle perfectly. (This is with 7 in the magazine and one in the bbl.) I should have tried loading six in the mag and one in the barrel, but for some reason I didn't.
2. Aguila SSS Sniper Subsonics, which regularly jam in my Bernardelli 60, feed perfectly. Two boxes (100 rounds) with not one misfeed. They *are* the dirtiest .22 round I've yet found, so there's probably a limit to how many you can fire.
3. CCI Stingers: I tried these after reading others say this was the perfect round for the Bobcat. Results? 100 rounds without a single FTF or FTE. I suspect the secret may be the plated case, which has a lower coefficient of friction than a plain brass case. Whatever the reason, I've found my load for this gun.
