I use the No 9 and the Mk2 in my guns depending on stroke, the No 9 is good and makes power easily but is a bit stiff to cock, I would like something in between ideally

I was a bit concerned that with so little preload that it would not keep the bounce in check, but it seems to shoot fine @ 25 yards, of to test it out to 55 this morning.

Mine( TX200) has a very light piston, and that does not bounce with the No 9, I do have a bit more spring room than standard though.
