Rifle choice is a personal matter, and if you don't know what you want, the task is impossible for someone who doesn't know you, or know how the rifle will be used. Not only must the action length, and bolt diameter be suitable for the cartridge you choose, you have to decide on the style and type of magazine (DBM, floorplate, blind, single stack, double stack etc), whether the rifle will be stainless or chrome-moly, blued, coated, or white, the stock material you prefer, and whether or not you want to try a custom barrel with an unusual contour or a nonstandard rate of twist. If the rifle wears iron sights, should the comb of the stock be low, or should it suit the mounting of a scope, and of so, will the scope have a large objective lens that requires it to be mounted high above the barrel? Do you intend to change the LOP of the rifle or even just change the style of recoil pad? If so a wood stock is easier to work with than plastic, fiberglass, or Kevlar. Do you think a fully adjustable trigger is desirable? Will the rifle wear a bi-pod? Do you use a sling as a shooting aid?
Under what conditions will the rifle be used? Will it be subjected to pack hunts on horse back, ride in boats, aircraft, snowmobiles, or quads? Do you intend to hunt in the mountains high above the tree line? Will the rifle be subjected to a salt water environment? Will the rifle be used in heavy cover? Will it be primarily an open country rifle? Do you intend to hunt dangerous game? Once you answer these questions for yourself, the choice of rifle brand, and style, factory, semi-custom, or full custom becomes easier.
