I was really wanting this rifle to like IMR7828, I use it in my 257. But 3 trips to the range with 3 different powders and this load has given me 1" groups or better every trip.

I read a lot of older post (some 10yrs old) where people use 4831 but  most of the newer ones have swapped to 7828, the RL's and some retumbo.

My rifle seems to favor this one though.

Hard to be upset about that group.

My 300 WBY likes that particular powder and 180gr. TSX more than anything else I have tried.  :)
