Well, I've hit the proverbial wall. I'm finally tired of my 338 LM, my 408 CheyTac, my 45-70 Siamese Mauser, and even my 260 Dingo (still my favorite caliber). I'm looking for a new caliber for a bolt gun. Have a few in mind, but I don't know much about the cartridges and much of what I read comes with a 50/50 love/hate response. Anyone have any experience with 20 BR, 204 Ruger, or any of the TCU cartridges out of a Savage bolt? I'm even considering a 458 SOCOM build seeing as I've had the opportunity to shoot one and boy, talk about scary accurate to 200...
