Hi chaps I am looking for some advice for a suitable RS powder for reloading 243. I use RS40 with my 223 and it works well and my local gunshop has good stocks of Rs powders. Im really just looking at a powder recommendation from RS 52,60,62 or 70 as in the book it gives load starts for all of them. Pushing 87Gr and maybe 65Gr Vmax if i can get hold of them. Im not looking for load data thanks just don't really want to buy more than one powder and wondered if anyone was using Rs in their 243.
