I have had the same experience as "Boo with 47SL [lot 10]Great 30-06 powder, with both 165 and 180 grain bullets. One of the most accurate loads I shoot out of my 30-06 M721 is 47SL and the Hornady 165FB. I have graphed it at 2910FPS, so it is definitely not too slow for this application. However, some years ago Higginson also marketed a lot of 47SL [lot 131] it was more like 785 Winchester and was a bit slow until you got to the 200 grain bullet. I still have a good quantity of lot 10, and probably 5 lbs of lot 131.Regards, Eagleye
