I've had a Crosman Nitro Venom for about a year, and like it really well. It's done for a ton of squirrels and some crows on my place. It's very accurate once sighted in, but the range isn't great and the trajectory is not flat - you must sight it in for the one distance that you will shoot at most. I have enough experience with mine now that I can make longer-than-sighted shots by a slight elevation of the cross hairs.I found this thread as I sit here an wait for my Crosman Nitro Venom air rifle to show up. It's my first air rifle, so I'm pumped (sorry for the cheesy pun). Hopefully tomorrow will be spent shooting several pellets to break it in and work on sighting the scope.
A really nice feature of the "nitro" models is that you can leave them cocked for extended times without harm.
