My 700 sps varmint in 22-250 is starting to get shot out and have been thinking of getting it re barreled. I'm thinking of going to 6.5 x 47 lapua. I already reload for my other rifles so ammo isn't an issue, but I would still like to be able to use it for predator hunting. Should I rebarrel to 22-250 with a faster twist or would the 6.5 be a good choice?
