Also note that in their current data, they list a max. load for RL22 and the 100 gr. TSX at 69 grains.
Myself, and I suspect many others who shoot the .257 Wby, have been loading 72 gr. for years, with success.
I noticed that too they were using 66.0 grains of imr 7828with 115. Versus everyone else was using 70grains with cup and core I tired 70grs with the 115tsx and shot just fine no pressure and a very accurate load I'm thinking of increasing the charge at .5 gr increments.
