Been watching a lot of videos, and really getting an itch to "build" one. I was going to try to find a Remington 700 ADL to butcher for the action. I looked at Krieger barrels, and this is where I start asking questions. Is their #9 contour "Heavy Target", heavy enough? I would like to build it as a .300 RUM, and get the barrel 26" , in a 1 in 8", with the 250 grain A-Tip in mind. The 300 PRC pushes the 250 at 2700 according to Hornady. So would it be safe to say, the RUM will be in the 2850 range? With that velocity, it will stay supersonic out to 2200 yards, and hit the 2 mile mark right at 900 fps. Taking 7.8 seconds to get there. With a 300 yard zero, its 131" low at 1k. Stock, would probably just find something laminated, and bed the action. Would build it as a single shot. Anyway, basically spitballing, but I have a cousin with an ADL. Now to call him. Suggestions?
