Home Forums Hunting & Shooting Air Guns Homemade 357 air pistol

Well, I almost have this thing finished. It's a .357 caliber using my proprietary valve. I'm pulling 148 grain bullets from a bunch of 38 special that I have for testing and I'm exceeding the velocity of the 38 special at 798fps. Breech and barrel are machined together. Still have to make a cocking knob for the back of it and the rear connecting piece that goes from breech to pressure tube so that it doesn't have that shortcoming at the back of the barrel. I'll also 3D print a front barrel band with sight. I used a Crosman grip assembly for the simplicity and not having to make one.
