So far this powder is not working well in my 15" barrel T/C, settled on 30 gr of the stuff, average velocity is 2650, which is 180 fps over my pet load of 29 gr of IMR 4320 and the nosler 85 gr Bt. Groups are running from 2 to 4 inches with the same pattern, first round hits an inch high and slightly right of point of aim, the other two rounds hit to the left of point of aim and just a little low. Tech support at nosler recommends that I seat the bullets deeper, different powders might warrant deeper seating depth. Load data from Hodgdon shows that they used a 75 gr speer flat point, maybe this powder is only accurate with 75 gr bullets, can't understand that 10 grains in bullet wieght would make that much difference. I am going to try seating bullets a little deeper, it's almost time to start watering the lawn, maybe this stuff will work better as lawn fertilizer.
