Hold on pard......that Rem 700 will NEVER shoot that accurately with a lightweight barrel.
With a little tweaking by a good smith......and properly tuned ammo (ammo tuned to the barrel) you MIGHT get 1.5MOA at 100yds, but most likely 2.0.
The rifle is far more important than the scope.
Who said anything about a light barrel? My Rem 700 is the Varmint Synthetic, with the heavy barrel. With a used Tasco 4-14 scope I shoot under 1 MOA (when I do my part correctly) using Sierra 168 gr. Matchkings. I have yet to develop my own loads, but hopefully will this spring & summer. I expect that this will not only cut my cost per round, but result in a bit better accuracy. I am hoping for a consistant 3/4 MOA.
I agree that the rifle is more important than the scope, but the latter can help a lot at extended ranges, as you've indicated.
Aim small, miss small.
