Well, some will like this I suppose, but I went out yesterday to finally shoot my rifle that I had the misfire with to see what the problem was. I fired 8 rnds consecutively from the same box of Rem CoreLokt 150 gr ammo w/o issue, then, I put the round that hadn't fired in the chamber, and "click". Heavy dent in the primer, but no ignition. So, it wasn't the Mod 710, but that one round was the culprit. Anyway, this is the first issue I've ever had with this ammo in, heck I don't know, 30+ years I suppose. I will, however, call Remington and explain to them the details, and let them know that I followed their advice and tried to fire it again. Who knows, maybe I'll get a coupon for some more ammo.
