The Yellow Jackets took the lead for good on a Corey Bays 3-pointer at 18:06, which started a 14-2 run, and never looked back.
Macon shot 55 percent (17-of-31) in the first half with nine of its field goals coming on shots beyond the arc. R-MC used that hot shooting to take a 49-31 lead at the break and to off-set a 21-14 Shenandoah advantage on the boards.
Junior Jalyn Jarrett paced the Hornets in that opening stanza with 11 points in 14 minutes of action.
The 'Jackets had two players: Luke Neeley and Jon Nowell, hit in double figures in the first.
The second half brought more of the same as Macon shot 58 percent (19-of-33) and had an additional five 3-pointers.
This is the first time in 12 games that Chaney has not been the hosts' leading scorer.
"I was proud of our effort in the second half, coach Adam Walsh said. "Our effort and execution was much better tonight against them than the first time we played (on January 9). We only play a handful of teams two times during the year and it was good to see that we competed at a higher level tonight."
