Well, I rest my case that you have no case. What, that is a completely worthless jib that serves no purpose, I take it back.
If your case is that someone else does not make the case for you and asks to have it shown, well my conclusion is that you have no case worth discussion.
Everything can succeed and everything can fail. One failure, or a few successes make for a very weak case. Hell, Bella Twin took a world record grizzly with a 22 (probably a 22 short, but perhaps a 22 long rifle) and Gene Moe Killed a costal brown with a knife.
If limited data is all the data we have, then we have no choice but to use it. However, there is a whole lot of success data buried in the thread with a few people who don't like certain aspects (no exit, poor blood trails, Etc.). If you want to have a case, for your accusation of intellectual laziness, which you have now specifically leveled against me by the way, stop being intellectually lazy yourself and make a case. That case, to be worth considering, must show that the 223/TMK fails more than a commonly accepted alternative (say a 7 mag loaded with Accubonds).
For the record, it was my own attempt to actually make a case against the 223/TMK that lead to me accepting it, because I failed to find the data I expected that showed it not to work.
