Re: deer antelope caliber
6.5x47 would get my vote. Small rifle primers are everywhere and you won't give up much to the 260Rem. It is a very accurate caliber and with the 123grn bullet or 140grn. you will shoot as far as you need to take game.
My first thoughts though before I read what calibers you were looking for were the 270 or 25-06 category. Just a thought. Both smoking calibers and perfect for deer/antelope to 600yrds+.
