tadbart Posted February 22, 2019 Share Posted February 22, 2019 That's pretty cool, what we can do so far away. We do indeed live in interesting times. 1 1 Link to comment Share on other sites More sharing options...

MikeG36 Posted February 22, 2019 Share Posted February 22, 2019 They should use a 50 BMG API round. I'll bet that would put on an excellent show in space. Link to comment Share on other sites More sharing options...

jame Posted February 23, 2019 Share Posted February 23, 2019 If oxygen is required for a flame to take place, how can a bullet be fired? Link to comment Share on other sites More sharing options...

Mayhem like me Posted February 23, 2019 Share Posted February 23, 2019 Does the sealed cartridge hold the oxygen?Yes that’s why they fire underwater Also the reaction is self-sustaining burning gun powder produces oxygen FYI We good for firearms in Space Force Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

Mayhem like me Posted February 23, 2019 Share Posted February 23, 2019 Also think of no gravity pulling the bullet down no wind no atmospheric drag point of aim to infinity ......and beyond Sent from my iPhone using Tapatalk 1 Link to comment Share on other sites More sharing options...

And that gravity does slow the bullet, and the gravity from the front accelerates it, albeit by infinitesimal amounts. I'll hush now...
