Tomorrow I am going to try the 175gr Maker T-Rexx copper bullet in my 28 Nosler. There is no load data for this anywhere. I used Hammer and Barnes data along with QL data and came up with N570 at a starting load of 74gr. I loaded a string from 74 to 82 in one grain increments. Anyone see this as an issue? My OACL is 3.4550.
