Nah man, a guy was dming me on Instagram about parts needed to build an 8j airsoft gun lol
Quite literally this:I put an airsoft barrel on an airbow I made and got 39J.
That's above the speed of sound with a .48g BB.
Funnily enough, the BB reached a building 110m away barely faster than a 3J gun with the same ammo.
To be honest I would use the joules as a reference since you will presumably be shooting .38s anyway.As for the airsoft, 550 is the limit for the local fields.This was with .38g bbs, now I grabbed some .20, I will see what that is.
