I have a custom 28 Nosler that to date I have not been able to find the degree of accuracy I am satisfied with using all the usual powders and multiple bullets. I would like to try RL 26 with the Berger 180 and am looking for some guidelines for starting loads. Using both some interpolation as well as extrapolation I have come up with prob about 80 gr +/- from the Alliant web page. My chambering is such that it will accommodate the 195 gr Berger. Any suggestions, recommendations, guidance or prior experience for this load would be appreciated.
