purity sure H414 and W760 are the same. load data is the same. I've used that for 58-87 gr bullets in my 243. probably at its best with bullets between 70-90 gr.
I see this new powder StaBALL 6.5 is showing a big speed advantage in some 243 loads.
Ie 80gr bullets at 3500 and 70gr bullets at 3700fps, that's fair rocking along.
