Welcome Kevin! Red oak has a great reputation and z bad reputation at the same time. I personally like red oak very much. Many factors involved in limit of draw weight. Limb width, tillering profile(to some degree), acceptable set, length, draw length, heat treating etc. my experience is that red oak is only moderately improved by heat treating. It will tend to chrysal on the belly before failing under tension assuming thd tiller is very good. For a red oak bow 72" long 1.5in wide for 2/3 of the limb then tapering to nocks and stiff handle, 60lbs at 28" isn't unreasonable. Especially with a little heat treating .... Wouldn't put in a ton if reflex though. Good luck.
