The one I've "settled on" for my favorite:
56 grains of Reloader 17
Barnes TTSX 168 grain (tipped TSX)
Federal large rifle primer

This load cooks along at about 100fps faster than IMR 4350, without any pressure signs whatsoever. (RL17 is advertised to pick up speed at a more uniform pressure curve, and it does.)

I took Barnes technical advise and hold the bullet a full .070 from the lands, and it really does increase accuracy to sub moa in my 06. (this bullet likes a small jump)

don't know why more don't use RL17, as it is a sweetheart.
