From experience...usually the ones that are the most insecure are the ones yelling the loudest...LOL
I think (my opinion just like yours and everyone elses does not make them wrong or right) you would be hard pressed to beat an 06 for a top choice for an all round caliber. Not saying it can take any and everything, or that it can do it all. Just saying, don't see too many people learning to shoot on anything larger then the 06. Really don't see or hear of too many people shooting matches with a 375 H&H or match guns chambered for that round, and I don't think that there are too many match bullets in that caliber, heck you are hard pressed to find hunting bullets for it in a store. Since alot of people don't load, this is a big factor. Now you do hear of them using the 375 H&H (why no vote for the 375 Ruger?) in Africa for varmints, but not so much here (not saying there are not a few). Where as I bet you can find a few more people around that shoot varmints with thier 06. I think that the main reason they use the 375 in Africa for varmints is mainly cause thats what they have avilable to them, and you never know what might come up on you. Since the average Joe is not going to be running off to Africa or hunting brown bear ALL the time, then my vote goes to the 30-06 all things considered...with the 308, 270, and 280/7mm mag not far behind...Oh, and I do think the 30-30 should be in the running as well. Now if there were a few larger animals that needed all that extra energy or more man eaters around...then it might be a different story...but I bet we would still have heated discussions over whice round was the "best".
