Not looking to shoot that velocity, mostly concern on the reading of my radarchron
Did some backyard velocity check on two old spyder I am selling locally and my Radarchron is showing velocity of 400 fps. Last time I shot a spyder was several years ago with C02 so I dont know whats needed to shoot a spyder without a HPR on HPA.
They are just stock classic side cocking spyder with stock oversize 693 barrel using .682 ball. Both without reg, one with an expansion chamber and the other with macro between the ASA to the lower tube (similar setup as spyder victor). Shooting on HPA tank
even if I play eith the velocity adjuster the number wont change. I shoot quite close to my target (garbage bin gilled with tree branch) so can not see if the shoot look right by eye. Does not feel that quick.
could the large porting located only at last 1" end of those barrel could false the value?
Also it wont recock if there is no ball in the barrel. But shoot well with ball in barrel.
If not I guess will need to change the spring to a stiffer spring on the valve or a lighter spring at the hammer
