Ive just used 2209 or 2208. cheap and works well. have used these powders for 65gners right upto 95gners(targex).
Ive used the 95gn targex a little bit. worked well. shot two bull tahr with them both one shot kills.
the 87gn bergers are also nice if you can afford them.
my favorite load is 87gn Hornady BT HP with 2209. they just seem to work really in my gun and on all the game I have shot.
