    Tuning Dwell time follow up (where’s the pellet)

    I found an article by Bob Sternes in Hard Air Magazine that answers my question about pellet acceleration and some rationale about dwell time settings vs pellet travel down the barrel. Not sure how this effects accuracy but seems like closing the valve when the pellet is halfway to the muzzle is...

    Tuning Dwell time questions

    Trying to get a better understanding of where dwell time fits in the tuning process. I understand that at best you are just wasting air if the valve is open after the pellet has left the barrel. Working with Delta Wolf so all is electronic. 1) Is the acceleration of the pellet linear? If...

Saw a big change in regulator pressure taking the gun from my basement at 68F to my shooting bench at 88F; 174 bar to 157 bar. In factory mode the DW wants to see 170 bar and instructions...

    Hi all, Been shooting JSB Beasts with fair results but seem to almost always have a flyer in five shot groups and want to see if this gun can get MOA groups at 80-100 yards. What ammo and results are you getting in .22?

    Compressor moisture example

    Hi all, It was time to change the output filter on my compressor so I was able to measure how much moisture has resulted over about ten months of use. During this time I have topped off a 6.8 liter tank from ~170 to 300 bar eleven times. There is a dehumidifier in the basement near the...
