I recently bought a Remington 700SPS chambered in 6.8 Rem SPC for $500. It's not really the caliber I wanted but it came with what looks like a HS Prec. aluminum bedded stock. So I figured that the stock and action is worth the price. My theory was that I could rechamber it and be good to go. Is there any caliber that uses the same bolt face dia.? What caliber should I change it to? I would like something that doesn't kick like a mule and cheap so shoot. I already own a .308, 22-250AI, and an AR15 in .223. I do reload for all of these so far. Any opinions on what to do?
