Been testing this latest WW XS 36-1 kit for a while and have finally finished testing, I have gone for smoothness rather than full power, the test rifle is producing bang on 10 ft lbs power, very little recoil and a nice smooth cocking action. I tried the rifle at a higher power but it became a bit erratic and was quite harsh to fire. i opted for a slightly softer spring set up so its now a real nice rifle to shoot.
