I don't underestand what you mean by "none were adequate".... You shot 6 bullets and droped 5 deers, I think thats sums it all up. No body is arguing with you about bullet placement. Even a poor bullet placement from a 375 h&h would not drop a deer. The whole point I was trying to make was that the .223 has ENOUGH power to drop a deer in its tracks as long as the hunter does his part.
A hunter who has shot much game would never make such comments. While others have done an excellent job answering your post, since it was directed to me I'll respond too.
The actions of the animals after being shot, along with the size of the wound channels, clearly indicated that had I shot the deer under less ideal circumstances I could have lost a few in thick brush, etc. while they suffered. Simply
killing an animal is not the goal of the hunter - it is to
quickly and
humanely kill while minimizing the risk of loss of the animal. Many less-experienced hunters do not seem to understand this concept.
Obviously you have not shot a deer with a .375 H&H. A hit which would have only pained a deer with the .223 bullet would have profoundly effected him with the .375. I've seen this often on Kodiak, where my hunting partners often carried heavy rifles in case of brownie encounters. The urban legend that a .22RF is no worse than a .458 in the gut is just that - legend. You have a much better chance of animal recovery with the big gun.
Obtain
enough experience actually killing game, rather than just reading about it, and you may change your outlook. Good luck on your next hunt.
