This first one is a TAU 7, .22cal CO2 pistol. I have it set up as a bulk fill. I use a five pound CO2 cylinder and a transfer tank.
The transfer tank comes with the pistol and holds 150 grams liquid CO2. I put it in the freezer for about 15 minutes, and then turn the 5lb
tank upside down and fill it. I use a postal scale to weigh the transfer tank to make sure it is not over filled. Otherwise, when it heats up,
it can explode.
I get about 300 shots from a fill. When getting low, I notice shots getting lower on the target. I had a scope on it, that I have since transfered to another gun. It comes with a scope attachment that is not in the photo. From a rest, I can shoot good pellets like
JSB into one hole. That's at 30 feet. Sometimes it gets boring at times.
It has a "muzzle device" on the 12 inch barrel that diverts the CO2 outwards through the holes, so it does'nt "follow" the pellet and push it off course. It has a gap, and kind of a cone/venturi. The pellet goes through the space, and as the CO2 expands, it goes around the cone and gets diverted outwards. It also came with barrel weights, a rod that screws into the rear of the pistol with an adjustable sliding
weight. The grip is hand fitted. With the weights adjusted properly, you can loosen your grip to almost nothing, and the pistol just stays level. This is my first try at uploading a picture. So, here goes-
