Hey Harry,
That's the 18 inch .22 barrel. They also sell 18 inch .177 as well as a 24 inch .177 and .22 I think I also saw on the Air Force website that they offer a .20 cal barrel also.
I've already started saving my pennies for some accessories for the rifle,,, my first purchase will probably be a .177 barrel to use for birds at the duck farm.
As for whether it's loud,,,,, yes it is, but having shot the Talon, Talon SS and the Condor at Cobra Airguns I was well aware of the sound levels. I'm not concerned with the noise as I will be using the rifle out in the field for hunting and won't be shooting it in my backyard. I went with the Talon over the SS because I wanted the longer barrel and I like the way it looks. As for the FPE,,,, I guess it's in the range you mentioned, but then I'll be the first to admit that being able to compute FPE,,, or anything else mathematical, is not one of my skills :) What I can tell you is that at 40 yards I was blasting through my 3/4 inch plywood target backing with ease and I didn't even have the rifle cranked up to full power.
As for the longer barrels giving more FPE or FPS I guess the longer barrels permit the pellet to obtain more energy from the available amount of air??? I don't know,,,, but I'll bet PeakChic or one of the others who are good at that stuff could explain it easily. Me??? I just point my gun at critters and take em down for dinner without doing the math :) Seriously though, I'd like to hear a simple, clear explanation myself.....
As for being fun,,,,, Harry I had such a blast with this rifle yesterday that I'm actually depressed that I have to go back to work today and won't be able to go out for another hunt.... This rifle is really gonna be a fantastic hunting tool for me. It's small, light, easy to swing on target, easy to shoot, easy to load, accurate, has adjustable power settings to suit my hunting needs, has a ton of accessories that can be obtained, can be changed to a different caliber in a matter of minutes,,,, heck,,,, the only thing the rifle doesn't do is run out and pick up the game for you after you kill it :) I know I still have alot of shooting and experimenting to do with the rifle before I will be able to fully utilize it's capabilities but that's gonna be 1/2 the fun.
I still love my springers and will continue to do most of my hunting with them, but I'm really glad I decided to enter the DARK SIDE :)
