Shooting at right around 550 with a .2 but I have no idea with the .36s that I use. It's hitting the target (bare part of tree) 7-8 times out of 10 times. I used a meter wheel clicker thing that rolls on the ground and clicks every meter to measure. When I got to the hedge I stood up a ladder so I'd know where to start from, walked around the hedge and continued. Now it is about 108 meters to the base of the tree, but since the target is part way up doesn't it shorten the distance a bit? As for internals it has a new hop up rubber, tightbore, deans connectors, new spring, motor, and piston. I take no credit what so ever for installing them, because I'm just not comfortable with possibly throwing away $800 and the parts.
