The old "addage" that a given barrel chambered for a given cartridge "likes" a particular load recipie has always puzzled me. Especially when over decades of competitive rifle shooting, every .308 Win. chambered barrel of all types with a given twist I've observed "liked" the same load recipie. They all shot very good in the hands of top ranked competitors winning matches and setting matches with virtually the same load with different barrels.
And unless the barrel's got horrible bore, groove and/or chamber dimensions, they all shoot good commercial match ammo as well as gumming match ammo very well indeed.
Perhaps there's something besides the thouands of recipies out there that are liked by as many barrels that's the reason. Could it be some other variable that's not being considered is the reason?
