velocities
Hi Guys
I did some tests with my talon SS.
I chronied my gun and got the following results
JSB 14grs 1275 fps (to fast I know)
enjins 23.6 grs. 980 fps (perfect)
I moved the Chrony to 25 metres. Results were interesting
JSB 14grs 950 fps
enjins 23.6 grs 930 fps
It appers as if the heaveier pellet retains it velocity better. So does this mean that on long shots the drop of a heavy pellet is Less? Higher velocity less “air time” less “gravity effect”, less Drop. Or am I going
blonde?
thanx

Oh, that makes sense; the reference to a Talon SS made me think 12″
it is a .20 with a 24″ barrel and a Blodnob valve. I recon I can get the enjins over 1000fps with a stronger spring. when I fill the tank to 3000psi my velocities are lower as the spring can’t open the valve fully, they come into their own at about 2500psi.
So . . . what did you do to get those kinds of velocities with a 12″ barrel?
Psion,
Yes, the heavier pellet has a higher sectional density which rolls up into a higher BC and less drop. Try your experiment again at 50 meters and you’ll see more of the same. Your heavy pellet will be well above your light pellet in velocity and on target. Mass usually out performs velocity in airguns. There is of course, a point of diminishing returns, but you’re not there yet. With the power you’re developing, the higher BC of the heavy pellets and the recoil pattern of heavy pellets will result in less drop for the heavy pellets.
Yes a fast moving heavy pellet will have a flatter trajectory at distance than a lighter one. Obviously you’ve done some things to your SS to get those kind of numbers.
