momentum=recoil, simply mass x speed
momentum goes up proportonately with recoil. ENERGY, however, goes up with the SQUARE of any velocity increase. That's VERY nice, because a 55 gr 223 sp, at 2700 fps, has the same recoil as does a 230 gr .45, at 950 fps (from a carbine) yet, when you shoot, say, ferale dogs with such a 45 ball rd in the carbine, they almost always run off yelpiing, to fall MAYBE within 50m, but often to make it 100m or more. Letting the enemy fire back at you, for 5-10 seconds after you hit him (at pistol type ranges)is an ASININE idea. The 55 gr 223 sp nearly always knocks the dogs off of their feet (given a solid chest hit)and they CAN'T regain their ability to run. So it IS energy transfer that you WANT in your ccw pistol load, but normal ammo offers very little such. That's why I went in search of the extreme pistol performance that I did. The 70 gr 460 Rowland Split Nose prefrag(3 segements) does the SAME thing to the dogs that the 223 sp does. Yet it's JUST as contolable in a lw Commander, as is .45 ACP ball ammo.
