First hunting rifle I bought for myself was a Savage 111 package deal in .30-06. Whole thing cost $500 from S.I.R not long before they got bought out by Cabelas, and the package gun didn't have the Accutrigger. Fast forward to now, and that same rifle has been restocked in a Boyd's thumbhole stock, I've slicked up and lightened the trigger a bit, and it wears a Bushnell Elite 3200 scope. Took my first deer, first bear and first moose with that rifle. I have many others, and others I hunt with, but this one will never leave me. .30-06 will kill anything on the continent, I can get ammo almost anywhere.
Younger guys and fad queens say what you want: there are many reasons the .30-06 is, and remains, the #1 hunting caliber in North America. Probably will be for a long time, everything else has a LOT of catching up to do.
