Another for the 30-06
I appreciate that there are those who caution against thinking that one long gun can do all things, but when I read the threads here asking what is to be hunted, where, at what range, etc., I can't help but think that the old 30-06 probably comes as close as any to fitting that bill. Perhaps not all the way, but real close.
In the same breath I will admit little experience with the other choices mentioned in this thread, so I'm certainly not debating the issue. But the guy who can't afford, or doesn't desire to purchase, an armory of weapons, might be interested in something which has at least a long history in its favor.
I will admit that my marvelous .03 makes me (probably unfairly) prejudiced in favor of the versatile 30-06, but it is a fact that for some almost 50 years I have loaded various ammo for her which I have used hunting rabbits in Texas on one end and brownies in Alaska on the other. Perhaps a little tough on rabbits, but it doesn't matter when a head shot is always expected.
The elderly '03 is a very flexible and dependable weapon which has never let me down. I fashioned her fiberglas-bedded stock, free-floating, scoped her with a flip-mount (invaluable in wooded brownie country), and finished her off with the necessary safety modification and a Timney trigger. Nothing complicated or difficult, but the result was well-worth the effort.
Hard to beat the '03 and 30-06 in one package.
All the best,
Jim
