I have tried to figure this out with the ggdt. I want to shoot nerf rockets from a 2x26"ish barrel with a 1" modded sprinkler valve at around 100psi. A 3" or 4" chamber should be about how large? I finished prototyping the breach loader tonight. If I can get the chamber small enough it will be an inline.
I cant figure the ggdt out yet.

A 1:1 ratio is more than enough, so 10" of 3" pipe or 6" of 4" pipe will suffice.

Thanks. I was pretty sure about it but wanted a second opinion.
