I am working on a project and am thinking about doing a 22-250 AI with 75gr A-max bullets for a little long range shooting/chucking. I have a 1:9 twist 26" Savage takeoff barrel from my .223 that shoots lights out to rechamber. I am in the process of getting a Savage action with accutrigger and .473 bolt face to use so it should mate up well. I am also concidering a 220 Swift Improved or a 22-243 wildcat. Pushing a 75gr Amax to around 3500-3600fps yields some amazing ballistics!! Any thoughts on this setup? Any other calibers you would reccomend?
