View Full Version : Calibrating Gelatin blocks

January 31, 2000, 04:33 PM
I want to thank Slim for Slim's help in my
last topic posted in the General Forum.:|)

I want to apply IWBA's testing standards and
that means I must calibrate my gelatin blocks
with BB's at a specific speed.

Can anyone help me with that process? Which BB gun to get, how to get the BB's speed up
to 590 ft/sec? :o
