My 26 Nosler isn’t picky, don’t see why the Wby would be. I would try the 140 Accubond. I use 869 powder in my 26, great groups. I would load to factory length, see how it shoots. Maybe try a box of factory shells first. Weatherby cartridges have free bore.
140 NAB is a great choice.
I've had good results with 120 TTSX and E-Tips, equal performance. At 3,450 fps and not pushing them, they are very accurate (half MOA) and at that speed, mess up tissue with DRT kills.
