Just getting back in to shooting again and need advice. I used to shoot a 22-250 but most shots were limited to 500 yds. and under. I know the 22-250 is a tack driver at this distance but now I have a location to shoot at 1000+ yds. I will be getting a Rem 700 SPS Varmint but should I stay with the 22-250 or go with the 308? I've heard of 1000 yard shots with the 22-250 so is there any real gain going to the 308?
