I bought a stainless Abolt 270, but have decided I don't want another 270. I currently don't have a stainless big game rifle and I'm pretty set on a 280ai. Should I build off of the Abolt or sell and buy a 700? I plan on shooting the 160 AB, but don't want to rule out the 175s. Barrel will be 22". Any advise on the rifle and or the cartridge is appreciated.
