Well I have a very inexpensive set up that hasn't fell me yet. I dont know if you have ever heard of rossi firearms. Its sort of like New england firearms and HR handi rifles. They are single shots. They come in both calibers you are looking for. I think a paid like 180 bucks for mine. I did top it off with a good scope though. A simmons 3-9x50. These guns can be just as accurate as you want them too. As a matter of fact, Im deadly accurate out to 200yds( sighted in at 200yds). Since most hunts are one shot only you cant go wrong with a single shot. One day I'll get me an expensive bolt action, only because i want a .243. But im in nursing and I cant afford one yet(dont laugh fellas im a manly nurse )

I WOULD GO WITH THE .270 OVER THE 25-06. AMMUNITION IS MORE POPULAR AND IT HAS A LITTLE MORE KILLING POWER.

OH BY THE WAY MY SINGLE SHOT IS CHAMBERED IN THE NUMBER ONE RECOMMENDED CALIBER. 30-06.

Although the specific model numbers escape me, Remington, Savage and Mossberg have very economical rifles available. Remington's number retailed for under $400.00 with scope included. Likewise, don't overlook the used gun market. I make it a habit of checking the bulletin board at our county municipal range and many times I see firearms listed for substantially less than fair market value. Most deer rifles see little use and remain in near-new condition, excluding those old lever actions that have been passed down through generations.
