I have used

H380, 4064, and 4895 with good results. Have continously obtained best accuracy/velocity combination with Sierra 150gr spitzer over 45.5gr 4064 with Federal 205 Match primer in Federal or Win. brass. That combo routinely gives 3-shot groups just under 1 inch from the bench. Of course different barrels may give varying results. With my 1-12 twist barrel 150gr bullets stabilize somewhat better than heavier weights.
