    Did he say 270 ftlb of recoil?????

    25400 ft/lb of muzzle energy. I wonder what you would shoot at?

    270 ft lb of recoil? Can that be correct? As I remember it takes about 70 - 100 joules to break an human arm.

    Isn't 270 ft lb about 360 joules?

    That's quite a round. Looks quite a bit like the .950 JDJ which can push a 3600 gr bullet (just over half a pound) @ 2200 fps. If memory serves, the rifles chambering it weighed in excess of 85 pounds and even then the recoil was s'posed to be vicious.

    ETA: Just for grins I ran both .950 JDJ projectiles through the Schwartz bullet penetration equation and got 135 inches of soft tissue penetration for the 3600 gr projectile @ 2200 fps and 90 inches of soft tissue penetration for the 2400 gr projectile @ 2200 fps. Whoa.

    There has to be an upper limit in caliber-bullet weight-recoil.

    It doesn't have anything on the 10mm. The only reason the 10mm doesn't rip your arm off when you shoot it is the bullet from the 10mm is so fast, the gun doesn't have time to recoil!

    This video is of the .950 JDJ. Quite an impressive round.
    38,685ft-lbs when loaded with the 3600gr projectile :wow:

    If only it were less than 2 meters across. You could blow up the Death Star with it!

    Why?

    Too heavy to carry for hunting.
    Too slow for armored vehicles.

    Agreed.

    May be able to do a little lathe work on a projectile tip (i.e. Tri-dart), add some good inards, and cure those problems though.
