Ok so I'm going to rechamber my Winchester model 70 300wsm. Its a post 64 with a short action. I have 3 other .300's so I was thinking since I'm re barreling I should change to a caliber that is more affordable to shoot. It will be just for 1000 yard or so targets and maybe antelope. What's a good caliber I can change my short action m70 to that would be cheaper to shoot
