I agree totally and I think these Indians were a little to young. As soon as a kid is able to hold a rifle dad slams a 223 in there hand takes them to the range let's them shoot 5 times and thinks they're ready for the woods. An older gentleman that hunts in our club said it best I think "a 223 is not a kids gun it's a experts gun". A well placed shot will do the trick everytime but a poorly placed shot with a round that small leads to a very slow and uncertain death. That was the point I was trying to make. Everytime Ive seen one used it usually turned out more complicated and less ethical than it had to be.
I do agree that a .223 is more effective when used by someone with skill and confidence in their shooting and having said that, there have been a lot of animals shot with the big game calibers that have died a slow death and never recovered.
I also agree that many young hunters get their first introduction to big game hunting using the .223 just because of the light recoil, ammo availability, price and it's just easy to teach someone to shoot them simply because they are a shooter friendly round.
There are a lot of better choices for young shooters who may not place a shot exactly in the right spot on an animal, since they no longer have a bullseye to aim at like they did at the range, and unfortunately the .223 is one of those calibers that you had better be able to duplicate what you do in practice, while out in the field.
The bone crushing 30-30 has mild recoil as does the 7.62x39, .357 Max, etc. and the .243.
Like I stated earlier if you are looking for cheap plinking and a proven hog caliber there is nothing wrong with the .223 but if you don't mind the added expense, and would rather have a little more potent round, then the .243 will pretty much do what you want, and without a doubt is a big step up from the .223.
