aalf - what load combination are you running in your 6x47s these days? I had one built several years back (Pierce action, Jewell, Bartlien 1-7.5, McMillan HTG), and due to life intrusions, haven't shot it in at least 3 years.
In the process of digging through my gear/records now, trying to piece together what I had been doing (I am horrible in the record keeping dept). I seem to recall that the 105/108s seemed to rule back then, powered by H4350. Looks like I was concentrating on the Berger 115gr with Reloader 17 and CCI 450s, loaded well on the hot side of what the Berger manual shows.
Thanks, mucho!
