I have a chance to look at a 30 year old Model 70. Friend of a friend type deal. I read in American Rifleman ( got it yesterday,.

), an interesting new book by Maj. John R. Plaster, titled "The History Of Sniping and Sharpshooting", I of course am interested the the latter

. Planning on ordering the book.
Hunting isn't my thing, but I enjoy having "good rifles." Even though I went to the "darkside" years ago, I love a nice bolt.
"These are my true riches. A man's worth is counted in the number of his rifles."
- Mulay Achmed Mohammed Raisuli the Magnificent(Sean Connery), The Wind and the Lion, John Milius(Warner Brothers, 1975)

I have a bolt action 1891 Argentine Mauser, 7.65x53. It's no joke and will reach out and "touch a target!".
I also have Winchester lever actions, but no Win. bolt actions.
What should I look for, outside the obvious,? Bolt tension? The Mauser is still "cycle it like you mean it". Should it be "stiff" but smooth, or should it be like "butter" all the way around?
What are the rifling specs? 1:7, 1:12?
Trigger feel,,? Anything to look for?
Tactical enough?

This was also in the article, thought it was "a good one", Wish I could find a Unertl 8X like the one pictured.
As always, I know the collective wisdom will put me on the path of enlightenment.

Thank you,
Tom W.
