It's on the list of potentials. This is for a 25x47L running 135 Bergers. Lots of anecdotal for H4350, some for N150, N540, N555 and a tip from a knowledgeable and successful F class chap on N550. I have 555, 60 & 62 to hand.RS60 is IMO one the finest powders out there
Very forgiving
We use it from 243 up to some magnums
Meters well in progressive machines
