I am thinking of building a .308 off of a 700 action and cutting the barrel length at 16". I have a #7 contour douglas match barrel. Has anyone done any chronographing with that short of a barrel and what powders would i want to use to get the most powder burnt with that short of a barrel. Also would it be a decent idea to ackley it to try make up for some of the loss in velocity on the barrel length. Thanks.
