I shot it through the chronograph today (No target shooting yet) It holds air after 6 pumps and up. I think I can get higher fps with a different valve spring. The original steel one just seams to be real stiff and I think that is why it holds air after only 6 pumps. Also my barrel is REAL tight. It's so tight I actually double checked to make sure I was using a .177 instead of a .22. I actually have to push the pellet into the barrel with the bolt and it's just as tight at the mussel end. They don't just slid in like my 101. I also got the peep sight and the knurled adjusting nut with mine like Elroy did. 6 pumps 458 fps8 pumps 558 fps10 ------- 569 fps12 ------- 591 fps
