All I know is my RAR doesnt shoot anywhere near as good as my T3.
The action on the RAR looks and feels like it was machined by a drunk gorilla with a rock. There are machine ridges inside the action that are easily 1/32" high and it sounds like hitting rumble strips along the highway every time I close the bolt. I'm not complaining about it, but that is what it is.
Compare that to the action on a T3. No, you cant, there is no comparison. If I get my RAR shooting for groups I'll gladly overlook the shoddy quality and clunky brick of a bolt.
I can feed my T3 just about any combination of powder/bullet in my handloads and it shoots MOA. Dial it down to the powder charge and bullets it likes and it shoots 3/8 to 1/2" groups.
I've seen some impressive groups posted here from the Ruger, but have only found ONE load that will shoot MOA in mine.
