Tuning After upgradation of RAW HM1000X .22

I can get as low as 750 fps with 18 grain jsb and as high as 1000 fps with 25 grain jsb redesigned. 

Both at 145 reg pressure. 

Just replacement of TP and adjustment of HST.

It takes 5 minutes as for change of TP, scope is to be removed. 

I didn't do complete shot count due to availability issues of pellets.
