About how much psi is needed to propel a foam bullet around 300 fps? By foam bullet I mean any type of nerd dart (homemade, or stock) that can actually get up to 300 fps without destroying itself while at the same time being accurate and safe. Are there any ways I could calculate how much psi I would need to propel a round of that type at a given fps myself?
Any helpful answers will be appreciated. Thanks!
