I shot the Disc 45 most of the year. My gun likes 110 grains of Blackhorn 209 with a Bloodline 200 grain in a Harvester light blue crush rib. I killed a nice 9 point at two hundred and seventy six yards this year. The 185 Bloodline works well with 100 grains of Blackhorn. Easy clean up. I tried a prototype 150 bloodline in front of 150 grains of Blackhorn. It was clocked at a little over 2700 but had no accuracy. The same bullet with 100 grains of Blackhorn is a three shot one hole gun. Good Luck
