I was following another build few years back on another forum and it is definitely an interesting cartridge. That fellow used .243 ammo to fireform then later tried .260 ammo which he felt worked better. Velocities were far better than I expected to see in a 22" barrel. Being 08 parent case, shorter COAL, using a mono other than lightweight would eat case capacity big time. I would consider using lighter Barnes or Hammer to get velocity needed to drive a mono. You got me thinking! I have a 700SA looking for new build and I like anything .270!!!
Thanks! I think!
