I got my MGM Encore barrel today in 30-40 Krag…
I am planning on shooting the NOE 311-202-RN out of it…
Since the 311-202-RN is a bore rider I am curious as to how far the nose of the boolit should be into the rifling—if at all…
I seated a few just messing with it and I am getting marks on the nose even when the boolit is seated deeper than the crimp groove (although that front groove may still be classified as a lube groove also)…
I wonder if that boolit is to be seated over the front driving band and crimped at that location…
Without doing fairly precise measuring, I think if the boolit was seated that deep into the case, the rifling might not contact the nose of the boolit…
How much is too much for the nose to actually contact the rifling?...
Thanks…BCB
