Alright guys I was cleaning both of my old L61r .270’s I was looking at the rifling and the the older of the two has twice as much rifling in it one is 1-9 twist the other is 1-10 twist the 1964 model is the one with twice as much rifling and the other is a 1968 model.
Any information on this would be good to hear!
