How many shots per fill?

 

[zx10wall]

How many shots per fill?

About 30.

 

[L.Leon]

About 30.

Shot count seems low, I notice your regulator is set at 170 BAR. The following is a few shot strings through my .22 Pathfinder Regulator at 150 BAR, HS as received from AOA. I get at least 70 shots from a 240-250 BAR fill.

What is the barrel length?

 

[L.Leon]

What is the barrel length?

10”

 

[zx10wall]

Takes a lot to get a .177 pellet shooting 19.5 FPE from a 10” barrel. It’s good.

Did not consider that. Was just curious, thanks!

10”

Yea i thought perhaps he had a longer 1

 

[Solo1]

Thats I don’t get why they didn’t put a slightly longer barrel on that gun i would think 2-3” more would be great for the power and not have to push so much air out right behind the pellet

I agree a 12“ barrel would be sweet. If they ever offer it as an option I would buy one.

I think this pistol is being made for a teammate for field target work. So the barrel can't be any longer than 15 inches which includes a moderator if I am correct.

What is pathfinder length with Stock unfolded but not extended at all? Can someone please confirm?
