I am confident that i will want to shoot 1000 or more. as long as i can hold steady with this light of a gun. ---here is what we have--- Remington trued action mag. bolt face jewell trigger ABS 26in carbonfiber varmate contour-due end of month titanium muzzle break lone wolf summit stock-on order Nightforce 2.5x10.32 -need to order total weight just over 7 with scope i am sparing nothing for this gun any input would be great. i am thinking of chambering this in a 300RUM.what caliber do you guys think? i am wondering what you guys think for the hunting that i am going to do. i am also wondering if you guys know what the barrel life i can expect?would you do anything different?
