Don't own one but have shot several - great rifles. Take a little getting used to ergonomically but they can be set up very nicely. Designed for low pressure fills which I wish more manufacturers would do. This one runs at ~1300 psi. The valve and hammer setup is really optimized for near 20 ft lbs power levels. I always thought about having Tim build one for sub 12fpe some day but the guns weren't really designed for it which is a shame.
