Today I took advantage of unusually warm weather for January 1st and got the Cabela's Hawken out to the range and got it zeroed with its new sights.
It was shooting about 18" low and a little left at 50 yards with my initial load of 60 grains of 2Fg Goex, a .490 round ball, a 0.018" ticking patch lubed with Track of the Wolf's mink oil tallow, and a CCI No.11 cap.
Grouping with the 60 grain load was 3 to 4" from the bench. IOW, not very good. So, I increased the charge to 70 grains and the rifle started grouping nicely. My last three shot group is below. It's the one hole in the center.
That's 2 in the X-ring and one just outside it in the 10. I can certainly live with that. (The target is full of .22 holes from taking my daughter to the range.)
I still want to experiment with different charges, patch thicknesses, and ball size.
