I'm probably wrong about this, but I thought the transfer of the bullet's momentum was more important for incapacitating a target...in which case the 45-70 should win.
As I understand it, it takes .5mv^2 energy to make the bullet go fast, but it transfers m*v to the target.
Ironically, the Barrett sniper rifle is used in the U.K in disposing of "suspect packages" as part of bomb disposal, not as a sniper rifle, as it's considered too unsubtle.... (The current British Army sniper rifle uses .338 rounds).I wasn't even thinking about knockback, although I imagine that there could be a tiny bit, though not enough to be noticable given the mass of a human. I bet a chipmunk hit by a 12 guage slug might be knocked back some...or a human hit by a flak-88. Even though human knock-back is so tiny, it sure makes a nice cinematic action bit of fluff in some cases.
I do think that heavy bullets lose energy slower than light bullets and thus would have better attenuation numbers. Could that be one reason heavy sniper rifles are .50 instead of .223 with a huge charge?
take my ideas with a huge block of salt; I'm no ballistics guy.
in any case FF&S1 figures damage from muzzle energy, and thats worked okay for me so far, so why worry about it?
Yes, it's hogwash.i have been told but do not know for true:
Geneva conventions ban the use of .50 cal rounds (maybe from mg only?) specifically against humans, but against an object is ok. so U.S. soldiers are not shooting AT humans, they are attempting to disable their uniforms, or the stearing wheel of the vehicle being driven, etc... But NOT at the person.
anyone know if this is hogwash?
Here in Alaska some Native Americans use a .22 cal. rim fire to hunt grizzlies. They shoot them in the lung and wait for the bear to bleed to death. The bear thinks it was stung by a wasp or hornet and ignores the pain. The sound of the small caliber weapon will not carry as far or seem as close.
This is not the way I want to hunt bear or any large carnivorus animal. I would use a large caliber rifle.
The Colt 1911 was purchased by the US to stop an enemy the .38 had little effect on. The fact that the 1911 is still used today speaks for its effectiveness. Yes a 9mm has more rounds in its magazine and has better penetration but the .45 is a man killer. I'll stick with the .45.
The 9mm can spit out more rounds very quickly without reloading as much as the.45 but if you can hit what you are amming at the first one round does the trick with a .45. I am not a fan of 'spary and pray'.
Stupid question:
In Europe 9mm Luger is the ORIGINAL 9x19(1) while 9mm Parabellum is the modern 9x19 from the 1930s. The two cartridges are slightly different, the 9mm Para is more powerful. Is using 9mm Luger just a US-quirk or do they still load to the older variant instead of NATO-standard round? Does anyone have performance figures of a 9mm Luger from a Walter P38 or Browning High-Power?
