First chance back from the auction to finally test fire the Challenger pistol. I had the power adjustment turned way down as I dry fired it in the house. Just a little sound. Tested with a Crosman Premier 14.3 pellet. No sound at all and it was 110 FPS. So I turned it all the way up. It was literally like a 22 LR going off, yikes! The neighbors! That was 414 FPS. Turned it down and got a very pleasant pop and 300 FPS. Good for the backyard. Infinitely variable which gives you a lot of options and of course the shoots per cartridge depend on where you are with it. Further testing and accuracy will have to wait for a warmer day out on the backyard range. Looks good in a couple days.
Seriously at full power this is crazy loud!
