Update: At two hours I
wrapped them in foil... They already had some bones sticking out at the ends.
Bentley, thanks for the 275 vs. 225 suggestion.
In my "Hot Rodded" GMG, 225 is kinda like 275.
Anyway, thanks guys for the info on what I'm working with.
I bought them on a whim as they were marked down for quick sale and today was a rare opportunity to cook them as I normally have other stuff going on seven days a week.
