A couple of rookie questions...

I've just bought my son (12 year old) his first rifle for a cow elk hunt this year; it's a Remington Model 7 7mm-08 XCR.

My questions: Is the original factory stock worth bedding? Do I need to pillar bed it and/or bed the entire action? Is this something I can do on my own if I get a hold of the right book?

Many thanks in advance,

Jason
