Update: Day 2 had another 120 rounds through it.
100 of those were Federal 40Gr. RED BOX champion (Yesterday it was blue box). The other 20 were Remington 36Gr. Golden Bullets.
We had some failures today due to the Federal Champion. That stuff is crap (in this gun at least.)! You could FEEL the light recoiling rounds. I'd literally pull the trigger and say "let me guess, this next shot wont fire." It felt like shooting a bb pistol that the air was running out on for certain shots. Out of 100 I'd say I had 4/5 failures. All failure to feeds where the spent shell would eject but not puck up a new round due to the weak charge. That i even OK for me though. Better than I had with the last time I shot the P22 with 9 out of 10 failures. Even despite the crappiness of the ammo I can say that this gun is like a laser beam. Point and shoot. I always shoot STUFF as opposed to paper, so glass bottles, candles, 2 liters, etc. were just vanishing. The golden bullets were totally reliable. After the crappy ammo it started to get gummed up though and would sometimes not pick up the first round from a new mag (it would get stuck on the feed ramp) due being dirty. I cleaned and oiled it and it is back in action. All in all I am 100% thrilled with the purchase.
