Remington lists the muzzle velocity of their 180 gr. load at 1,150 fps which would be pretty hot for a .40 SW but not for the 10mm (assuming it really shoots at 1,150 fps). I don't shoot .40 SW but I can really tell the difference in .45 acp and 10mm. The .45 is not nearly as snappy as the 10mm.
Jim's Rules of Carry: 1. Any gun is better than no gun. 2. A gun that is reliable is better than a gun that is not. 3. A hole in the right place is better than a hole in the wrong place. 4. A bigger hole is a better hole.
no guns = might makes right
