I have been reading with great interest the posts on this site and have gleaned a lot of information. I am currently in the design phase for a new long range rifle. my current long range gun is a .300 Weatherby Accumark. The hunting I do requires quite a bit of horse back riding or walking to get into undisturbed areas. I will limit my shots to 700 yards or less. This rifle will be used for elk, deer, antelpe and hopefully sheep and mountain goats. I want to use a Remington Sendero action and stock. i will add a Jewel trigger and have the action blueprinted. I want to use the 7mm Ultra Mag. In a 28" Christesen Arms carbon fiber bull barrel. What do you guys think? What bullet and powder?
