[QUOTE="Clark, post: 1356872, member: 6600"] I am amazed to see the great 1990s gun forum poster Louis Boyd show up alive in 2017. My father made a parabolic taper hydraulic system for recoil in the 1950s on the M55 contract. The equation shows up much later in a different gun [URL]https://docs.google.com/viewer?url=patentimages.storage.googleapis.com/pdfs/US4353285.pdf[/URL] He was using this book [URL]https://www.amazon.com/dp/B016FU7YBG/?tag=lrhmag19-20[/URL] Hayes Elements of Ordinance. The math in that book is senior engineering or graduate level, but the center of the mass of the gas contribution to momentum is jr. high math. It is 4,000 fps. [/QUOTE]
