I need some education and opinions on titanium actions. What are the weight and other advantages over a milled down Rem 700? Are there any with other than 90 degree bolt lifts and possibly 3 position safeties? Which one would be best for a low ejection angle that would work well with large turret scopes mounted low? What are some considered the best that I could review more info on. I don't know much about them in general and want to educate myself.
