Shot GB's over chronograph today, 500 fps. I was a little surprised.
Put some paint on yesterdays creation.
My 'little brother' popped off a few rounds.

I borrowed it from a guy that loads his own pistol ammo.
New ones I think are $85. ? Try to get together with some other shooters.
Maybe meet once a month at a safe place to shoot?
Once you have speed figuring distance would be easy.

Yes, but if he had a job, he could afford both :D

Very nice, at that velocity you have a muzzle energy of around 380 ft/lbs - much more than a '38 special revolver round and three times the energy of a typical 22LR rimfire round :)

I just bought this chrony new for less than 80 bucks, it's an affordable bit of kit and very useful for advanced spud development.
