I have just ordered som Nosler Ballistic tip and Accubond in 180 grs for my 300WM.
Is there anybody in here who have a good load with good groupings to that bullets ?

If you share, i'l be happy

I used R22 and IMR 7828 with the 180 ballistic tip and both powders worked well in my 300 win mag.

74gr RL22,..seated at the lands with a 178 a-max (sub .5moa)

Yep.
