After getting the scope mount so graciously provided by usmcsgt0331, I installed it and my Weaver T10 on the rifle and zeroed it at 200 yards. I then did some testing with 169 gr. Sierra's with both 4064 and N140. Two of these loads looked good so I thought I would try them at 600 yards. The 4064 load was OK, but the N140 load was clearly better. I won't list the load here as that would be irresponsible, but I will post a picture of the shotmarker target with some explanation. Shot #S1 and S2 were cold bore sighters, Shot #2 was due to wind shift, #6 was called low. This is with the Remington factory barrel and shot prone with a sling. New Kreiger barrel is about 5 months out.
