There is a rifle match at Camp Robinson Arkansas every month. 600yds one day and 1000 the next. I'm planning on a 6.5 creedmoor build to be able to shoot both with one rifle. My question is this. Since I will be shooting off the ground will a heavy bull barrel be the best option?. Also when I order my stock do I need to tell them what contour barrel will be going in it. I notice the Bartlien barrels does not have a straight bull barrel, but most other barrel makers do? I wanted to go with bartlien and still may, but I need to figure out what contour I need. Any info would be great.
