OB Before Hornady published data I tried the 185 GMAX with a lighter load of 44.5 gr of 8208 and a 210M. About all I can say is I did not have any pressure signs accuracy was like 2" I did not have my chrono so no velocity. Since then Hornady has published data and their max is 44.4. I was in the same shape you were wondering what accuracy would be like I wanted to work up to the 47gr load that has shot well (5 in about 1") consistently with the 185TSX. Since then I obtained the Hornady number 10 and saw the published data and have not revisited.
In any case the 160 ttsx has proven itself to be quite exceptional and the 185TSX is darn good as well both with 8208 and 2230. If I have a need to use a bigger bullet the 210 SS2 and HLVR looks like a winning combo.
