It was a great morning for shooting. I had boresighted it (with great advice from members on this forum) and was on the paper at 25 yards. I made some adjustments and shot a group at 50 yards. I made some more adjustments, then shot this 3 shot group at 100 yards.

90 grains FFFG 777
200 grain XTP
MMP tan sabot
777 primer

Not too great, so I decided to switch to Harvestor sabots and 95 grains 777. I knew from past experience that 95 grains was this rifle's "sweet spot".
