180 grain Nosler BT atop 56 grains of IMR4831 sparked by CCI 200's gives me bug hole groups at 100 yds. My W760 load pushing 180 grain Accubonds was a failure. I tried varying charges of W760 with CCI 250's with them and all groups were minute of a broad side of a barn. Horrible groups. Seriously about three to five inches after firing five shots into one hole with the above mentioned 4831 load. What I have left loaded are getting pulled and reloaded with 4831.
