I have used 55.8gr. of H4350 and a 180gr as a basic 30.06 load. In a couple of rifles,a Browning and a Marlin,it is the load, As well ,I have tested it in four of other 30.06s,and it has always worked well. In the Browning,with the Interbond it was very accurate,well under an inch at 100m.I have found generally ,the Interbond to be more accurate than the Partion ,less than the SST.
