RE: 25-06
I'm not going to be a nay-sayer, but I will say that I personally think there are better choices. Here are a few reasons why:
First of all, in my experience, 25-06's can be fairly finicky when it comes to ammo. While this can be true of certain rifles in dang near ANY caliber, it seems to exemplify itself in the 25-06 more often than not. And by finicky, I don't mean that it will shoot Federals great but doesn't like Remingtons...oh no...not quite that simple, more like it won't shoot any factory ammo much better than another, but certainly none good as it should (think around 2" or so at 100). While thats not bad for some short barreled deep woods brush guns...this is supposed to be a 400 yard gun...and 2" at 100...ain't really gonna get it done on medium game and espeically not varmints. I have spent some serious time working with some of my customers and they have spent some serious time and money handloading to get them to shoot those nice .5" groups you hear about so often. There again...this isn't always the case, but considering how many 25-06s I have had contact with (5 if I remember right, 3 with issues...all the same problem), its a fairly high percentage. Keep in mind...might just be a bum steer on my part. Luck does work both ways sometimes.
I'd steer you more in the direction of a 6.5x55 (if you can find one) or the .260, which is just sweet! If you want to do more varminting with the occasional deer hunt...I'd recommened a 6mm Rem, or a .243, though I prefer the 6mm. If you are a handloader, then the 7mm-08 is the way to go. I have loaded some 100gr flat based bullets that shoot like lazers, and the handloads you can produce with 120gr bullets will shoot flatter than factory 25-06 ammo. Plus, you have the option of loading up to 175gr bullets for big game, should you choose to, although I think a 160gr option would be better.
Just some food for thought. Nothing wrong with the 25-06, lots of loyal fans and many deer killed. Just make sure no matter what you get, you put your money into the scope, rings and bases!
