What action would you use.
I am going on a Elk hunt, in western Montana this fall. I am going to build a long range rifle. 7mm mag. with a no. 5 contour barrel with a 1-10 twist I plan on using 168gr. Berger VLD bullets. What action would you use, Savage, Winchester model 70, or Rem. 700. I need your help with picking out the action. Thank you.
