Need some advice. Im having Kevin Rayhill of Stockade guns build me my first long range rifle. I was originally planning on a 308 but have now decided on going with a 7mm-08 with the 162 amax. Most all of my shooting will take place in the field prone or sitting with a bipod. I dont want it super heavy but would like a little weight there. Im wondering what your opinion would be on the optimal barrel length? After limited searching on the net, most ive found preferred around 22 inches but that was mainly on compact rifles. I was thinking 25-26 inch for mine? Would the longer barrel allow me to use a tad slower powder than usual for a bit more performance? I hope I made sense. Thanks for your help.
