I was shooting those bullets at 46 gr. of H4895 out of mine, so maybe I'll speed it up a bit with the 47.5 charge you use of IMR4895 to see what happens.
I used the H4895 because I looked on the burn rate chart and saw the IMR and the H are right next to each other on the chart, and figured it would be about the same, but maybe the IMR is slightly different, eh?
