So far I have shot that group TWO times. Like I said I am working up loads that give the best accuracy. That load has repeated itself. Granted I have only shot it twice, but both have been very good groups. This gun and shooter has shot three out of three shots in a 8 inch pie plate at 600 yards in the open fields of Iowa with factory ammo. The accuracy at that range is only going to get better with handloading.

If I were on here telling you how well I was shooting my .270 or my 30-06 at that range, the replies would be nice shooting, keep up the good work, but since I own a 30-378 this is all I hear.
