Life has been hectic but finally got a short range session in with mine, nice solid shooter. Similar experience to Luke's in that a wide increment charge ladder shot very well.
I was mainly shooting for velocity readings to figure out a suitable max charge for this combination. I wasn't shooting sloppy but left a little on the table admittedly in terms of aiming, wasn't anal about the last 1/4" or so of cross hair placement for each shot. So with that in mind a 1" 5 shot group at 200yd that had a 2gr spread in powder charge makes me quite optimistic about what this combination will do with actual loads shot for groups (would have been a 7shot across 3gr spread in powder charge if that 66gr was in the group, not sure if I pulled that one off hand). I was cleaning every 3rd shot as well (the red ones are the first shot after cleaning so could account for those flying at times, the 66gr is still off though).
