So lets say I just bought a new Stiller Predator action and 6mm Brux blank. Which bottom metal (or none -- ADL) should I be looking at? I'm not opposed to use something that affords longer OAL. I can have the chamber throated to my liking, but I don't want to rob case space either.

After the first barrel is burnt, I may want to jump to 260 or 7-08. Kinda looking post 243AI too. You never know....but now is the time to consider options.

I enjoy handguns and I really like shotguns,...but I love rifles!
