Although medical care wasn't as good 100 years ago, I'm not sure the goal was to wound and let them die slowly because you might get a bullet in return. In other words, the INTENT was to kill when you shot someone, so the little calibers must have had enough whump to do that.
Folks,
I think some of you MAY have mis-understood my discourse about the poor medical treatment available to a small caliber bullet-wounded person in the early-middle to late-middle 1800's. I think ALL the .31cal shooters DID INTEND to kill their assailants. BUT as you told in that second part, sometimes bullets don't do too much at all to a person.
I don't think the people who picked the .58 caliber rifles with Minie bullets for the Civil War thought that there would be as many wounded--rather than just the "killed instantly" enemy soldiers either. It must have been pretty horrible to have a single shot disintegrate the biggest bone in your body and if you are not unconscious from the pain or shock, you choose to take the amputation OR die from gangrene.
Once you had your claim jumper down from a bullet wound in the guts, you could take your time and put one through his eye or eye from about 3 inches away. Cruel, yet effective.
Think about the mentality of today's Army and that pipsqueak M-16 compared to the .30-06, 8x57mm, 7.62x64R .303 British, 7.7x58mm, all much more lethal guns that were used in WWII by the various sides. The goal nowadays is to just wound the enemy soldier so that 3 persons are involved in moving, caring, treating the wounds. That logic might work if the enemy CARES about their people. Most of the trash that the USA has been fighting since WWII don't give a rat's butt about their civilians, let alone their soldiers.
They must be figuring this out, cause many military are now switching back to the .45 ACP and now they have that 6.8 SPC round that will work in a slightly modified M-16. At least they are headed in the right direction. I've shot a Beretta 92 9mm and a Colt 1911 .45 and the power difference is obvious on a piece of 2 x 4. Also the Colt is absolutely reliable in all conditions and it was never meant as a primary offensive weapon--too many people watching movies and TV shows about guys using their 9mm large capacity pistol to shoot at bad guys 100yds away. The pistol was meant as a close range weapon (no more than 25yds and more like closer than 25 FEET!) and for that purpose there is nothing like a good old Colt .45 Auto. But that's getting a little bit OT... it does illustrate how things were/are though.
Let me ask you though... which caliber cap-n-ball would you pick as your self-defense sidearm in the 1860's, IF cost or availability of the supplies didn't make any difference...? I'd have probably looked for one of the 3rd model Dragoons, or any of the Dragoons or a Walker if available. Can't beat that "extra whompus" factor.
Being "over-gunned" (I call that well prepared!) was never a disadvantage in any normal battle or gun fight situation that I've ever read or heard of. Don't think that will ever change either. Size does matter in pistol fights!
ALWAYS use a BIG enough gun,
