What overall length you loading?
46gr gave me 2856 loaded 0.03 off with oal of 2.89. Plan to experiment and try for an accuracy load. 47 would get me very close to 2900 but accuracy is what I want. My barrel is 30". This bullet and R26 looks like it has real potential.So that it fits in my short Rem magazine. 2.81 or so, I think.
