I was testing muzzle energy for different weights to try and get an idea of which BB to use in my CYMA CM.701b (428mm barrel VSR). I found that 0.45g were firing at 1.7J, 0.4g at 1.8J and 0.36g at 1.9J.
The rule you tend to hear is go as heavy as you can hop but there has to be a point at which the initial energy of the lighter BB is so much larger than that of the heavier BB that the effective range of the lighter BB will be higher. Is there a formula for energy loss over distance for given BB weights I can use to determine this?
