I am cooking a rib roast for the guys at work.
If I grill it at 250-275 how long am I expecting this to take?
I know this is approximate but am I looking at 3 hrs
or am I looking closer to 5.
Looking for any advise anyone has.

closer to 5-6 hours to get to medium rare if it is a large diameter roast. If it is a longer roast, then more like 4 hours. This assumes bone in.

Yes bone in and looking for medium rare.

Cook to 125* - 130* internal. That should get the center at rare and the outer portions to med/rare. Any longer and you risk the outer portions to be medioum to medium/well. Let's see some PRON. Want to know how a roast that big turn out.

I would cut it in half as Thirdeye suggest. Provides more end cuts for those that like it a little more done. Also more spice surface.
