Mf x Vf = Mp x Vp That is, Mass of the firer times Velocity of the firer equals Mass of the projectile time velocity of the projectile. (Sorry, proper subscripts are beyond my ability) Velocity is a vector, not scalar motion (that means it has a specific direction).I was wondering if there's a reason they can't be portable and hand held:
Hypothetically, a 4 ounce copper slug accelerating to say 6000 feet per second in a four hundredths of a second (and I'm being sloppy for ease of calculation) will...
Oh the heck with the numbers, this is like the weight of three .50 M2 bullets being pushed to more than twice the velocity of a .50 bullet. We're talking 25mm derringer here, but with a much higher muzzle velocity. Even if you could figure out a way to make this a cannon rather than an aimed bomb, the recoil would tear your shoulder off and probably cause all sorts of novel trauma. As it is, this is a bomb with a well focused directional effect. (or at least so far as I understand the physics of the Misznay-Schardin effect.)
RA, you bring up a good point, but EFPs are apparently at the very limit of improvised projectile weapons as it is. Of couse, some smart boy will come along and start pushing on that limit
Adam L,I think you're on the right lines, you've got to anneal the copper, but the quality control on the process is the difference between servicable and optimum (like the difference between an early Russian AK-47 and a Finnish Valmet; same general design, worlds apart in performance).Although I see how heat treating the copper could be important, I'm skeptical of how important,
