For the .25-06 I've had excellent results with Norma 204, MRP and VV N165. Norma 204 is my primary with the .25-06 and I stick with 100gr NBTs.
I'm still futzing around with the .223, but so far H-335 is okay, RS Xterminator shows promise as does TAC.
223...........
always have a bottle of Blue Dot on hand !
And lots of Sierra 40gr Varminters.
