I'm in the process of building a new rig. I like the 6.5 Creedmoor for a number of reasons and tend to accumulate them. At the range the other day, a new guy was trying his new build, a 6.5 PRC. Turned out he was a retired marksmanship instructor from Ft. Benning just down the road I was not familiar with the 6.5 PRC and checked it out. It was AR based with a muzzle break. Too loud. He hasn't received his can adapter yet. I thought this might be a new way to go since I could use the same bullets that I already use. When I got home, I looked up the 6.5 PRC and was impressed by the specs. When I talked it around, I found that it was just a little too long. High BC bullets with long noses past the ogive won't fit most magazines and still get the right jump. It became a case of fitting the cartridge to the mag unless you want to fire single shot. All this being said, I ordered a 6.5 CM barrel yesterday. I know there will be those who disagree, but check it out closely before you do. It sure surprised me. I have a Ruger RPR that has that problem. I might just find a way to use the 6.5 PRC anyway.
