whats the go with bedding in a riffle barrel? i heard, from a fairly reliable source, that when the rifle is brand new, you go to the range with all your cleaning equipment... fire 1 shot, clean the barrel untill every bit of copper has been removed ten times. then take 2 shots and clean 10 times then take 3 shots and clean 10 times and so on and so forth untill you've fired 50 or so rounds? is this really that important? and will it help extend barrel life?
