I am going to be having a custom rifle built in either 280 ackley or 338-06 for all north american game besides brown bear. Which caliber would you choose and why? What would you have done to the rifle? The rifle im building off of is a remington model 700 sps stainless. Im thinking about putting the rifle in a Mcmillan Edge rifle stock. Is the Edge stock worth the money? Im looking for any ideas on this rifle as this is my first custom built rifle.
