The late Bob Milek spoke well of H4831 for making the 25-06 shine. Mine does exactly that with that powder. I have used both H4831 and H4831SC and have not seen any noticeable difference, except the short cut is easier to meter.
I use 100 gr. Speer SPs for everything and have had great results with them. I haven't used the bullet you mentioned.
Good luck with it. The 25-06 is a real winner.
