Thanks for the info Dave! I have another question for you now.
I was reading on the Pyramid air blog that the Marauder was extrememely quiet. Like if you were 50 yards away, you would not even hear it go off. Is that true? Is the Disco much louder?
If it really was that quiet, it would be worth the additional cost, just for the convenience of getting to shoot it in the back yard without all the neighbors hearing it.
Also, if I went the Maurader route instead, and I used the hand pump, is only pumping it to 2000 pounds a big disadvantage? I would only be looking to get a 14.3 grain pellet about 700 to 800 fps. I would think that a .22 pellet that speed would be great for rabbits out to 40 yards.
How many fills can you get out of a scuba tank?
