Others Crosman 1720T with Huma Regulator

[SAZ-2]

For anyone out there that has a 1720T pistol they use for PFT shooting at <12 fpe - AND - has installed a Huma or other regulator.
I have my reg. set at 125, HS preload 1 turn in from fully ccw, and HT in 0.25 turn from fully ccw.
It's working pretty good but I am just wondering what others (that know more about tuning) are doing.

I'd like to know:

• What pressure do you have your regulator set at ?
• What is your hammer spring preload from fully ccw ?
• What is your hammer throw from fully ccw ?

Thanks !

Got a reply from Motorhead with some suggestions.
Turn down reg a little bit, HS preload & HT adjustments, etc.
Thank You !

Leaves a lot of latitude for "customization"......but here it is.

baranjhn,
On second thought, it dawned on me that you may be interested in what my "current" settings ended up being ?
The 1720 is a lot more quiet with these settings also. Also switched up to the 0.120" transfer port.
More accurate than previously. Thank You Scott !
