20k rounds Huma Regulated Hatsan Flashpup

[Eldecar]

These things are rock solid. 35 yards and one hole groups with Walmart Crosman Premier HP! Wore the bluing off the bolt.

Nice. I like Hatsan rifles too. Very tunable with a Huma installed.

I've got one in 22 that I'd like to put a Huma in and try to tune it for heavier pellets.

I have 1 in stock 22cal.I have to use the single shot tray because the magazines (the red 1s) are troublesome. Must be deforming the pellets as they are loaded into the breach as accuracy is less than when using the sst. Really hits hard tho and likes JSBs 18 gr

Anybody possibly steer me to info on tuning a Flash series Hatsan.

I'd like to put a reg on it and I saw where there is also room for improvement in the porting as well.



Thanks
