All the rest of my .30 reloading is done mainly with cast bullets. With 30+ molds on hand, my boundaries are nigh limitless. The .300's are the only rifles I feed a lot of jacketed bullets, because that short neck is a bit of a PIA for cast bullets.
Tell ya what, Doc. If you're going to the Fest I'll bring a box of them along for you. If not, PM me your address and I'll mail them. On the other hand, I wonder how the 170 Core-Lokt would work in the .300 for deer...
