Yeah, at this point my thinking is somewhere in:

.300 Win Mag, .300 WSM, .300 Wthby Mag, .300 SAUM, .300 RUM, .338 Win Mag, .338 RUM, and .340 Wthby Mag.

Anybody want to convince me that I could/should go higher? Or maybe a non-magnum somewhere along those lines?

Actually, after I typed up this question, I went out to one of the area gun stores and worked a few of the bolts... I found out I like the Model 70 action almost as much as the Model 700 action I already work in my current gun, and that I don' t really think I like the Weatherby action. Other options?
