Nosler's recommendations are usually reliable. Here are the "Most Acccurate Powder Tested" and "Most Accurate Load Tested" with a 26" 1-10 twist wiseman barrel. Pick one of these bullet/powder combo's and bump it up and down 1-2 grains in 1/2 grain increments.
180gr Ballistic Tip, 62.0 gr W760 @ 2884fps (max is 66.0 @ 3071fps)
200gr Accubond, 62.5gr H4350 @ 2872fps (max is 64.5 @ 2925fps)
