I am getting ready to build a custom 300 win mag and need some input guys. So far the only thing I have bought is the barrel. I bought a Broughton C-5 5.75 1 to 11 twist barrel "finished length with be 26 inches". I also have a browning A-bolt stalker action laying around the house. Will the Browning make a good action? I plan on using the rifle for long distance shooting and some hunting. Open for suggestions from A to Z
