At this time I am shooting a Savage 10fp 308. I switched from a savage 11 300 wsm laminated thumbhole (Dick's sporting goods model), mainly for the cost savings in reloading, and I have a shooting partner who also shoots a 308. Turns out I'm happy with the change, better accuracy from the 10fp and I didn't have to invest in new reloading components. My interest is as much 1000 yard practice I can afford. My question, "Is there a better caliber to shoot out to 1000 yards taking into account nothing but cost of reloading and barrel life?"
