[QUOTE="jwp475, post: 390619, member: 3776"] And that relates to a specfiic volume of gas pushing a bullet down a bullet, how? It doesn't. For instance we have 50 grains of powder in the case producing 60,000 PSI of presure and this is producing 3000 FPS. Now lets reduce the bearing surface of the bullet which reduce the friction, now our 50 grain of powder is going to produce less pressure and of course less speed. We will then have to add more powder inorder to get back to 60,00 PSI and our original 3000 FPS [/QUOTE]
