I remember a while ago reading a post saying that you don’t need anymore than a 22” barrel on a 30-06. I am reading one of O’Connor’s books right now, and he is talking about ballistics. He states that factory ammo ballistics can’t really be relied on because the manufactures test guns are usually longer barreled then the standard hunting rifle. He stated that most 30-06 barrels are 22”, but that the ammo manufactures test with a 24” barrel. I notice that Remington puts a 22” on their BDL 30-06, but has a 24” on their CDL 30-06, does this mean the CDL will shoot the same rounds with more velocity? Does it also mean that the CDL will achieve advertised velocities from factory ammo, and the BDL wont?
