I have to ask - I shoot the Remington 770 in 308 - good gun when I was learning about guns and hunting. I am now looking to upgrade the rifle. Should I stick with the 308 or move into a different caliber? what would be the benefits of having multiple calibers other then "look I have a lot of guns". I hear that 270 WIN can take down everything in California. I have even read some guys who hand load taking down elk? Any thoughts?
