I want to try out up to 600 yard FT/R with a 223. I like underdogs and no recoil etc.
The setup will be a short standard action, machined recoil lug, SSS trigger, Choate Adjustable tactical stock, egw base, heavy duty rings of some sort.

For a barrel 7 twist and I would prefer a 26" varmint for handling, but know its an underdog so should I just bite the bullet and go for a 28-30" bull barrel ? Thinking a Criterion barrel.

Right now am considering a SS 20X milrad scope but may later upgrade to a Viper HS-T 6-24x50 milrad Riflescope when they come out.

Have no clue on a spotting scope except I know it will be expensive. Thinking Vortex or Nikon. Want to be able to see 223 hits at 600.
What works best ? I assume a straight scope since I will be prone.

Thanks
