Re: what caliber? .243 win or 250 savage?
.25-06 would get you some more gas, but of the two, I'd say .243.....More common and great BC bullets are now available. As far as what to get, I'd get either remington 700, Howa 1500/Vanguard SII, or a Savage. Any of those are cheap with tons of aftermarket support for later. If you want a really great action(smooth) with a really great trigger(crispy like a cracker) Tikka t3. All of these will fit your need nicely. Handle some and see what you like.
