Not sure if you have seen my message. I have REM 700 G2 barreled action with trigger. It has under 500 rounds for sure and eaily prints .3-.5 groups at 100 years with my custom loads of 175 grs Nosler RDFs and 43 grs of Varget. See its targets and I have picture of it when it was in MTD 21 chassis (which I also still have).
I do not use this one as I have built custom 223 AI for reduced recoil.
Pls. let me kow if you are interested.
