Hi,
After having a failure on the primary ejection charge because the hole was too
big (back up charge worked). I started to search the web for a vent hole
calculator (not av bay). But I couldn't find one. Does anyone have a formula or
calculator for this? The body tube is 610mm tall, 98mm in diameter and the hole
size was 6mm (24', 4' and 1/4' roughly).
