I have some minimal reloading expierence with .223 but nothing near as in depth needed for this type of shooting. I just ordered a rifle from MPA chambered in 6.5x47. I also just received 300 rounds of new lapua brass and an 8 lb keg of H4350. I also received my set of Redding dies and competition case holders as well as my bushing, can't remember the size but I want to say 289. For primers I was thinking of going with cci450 and bullets was thinking nosler rdf 140 grain. My main question is with Case prep. I've heard about firing all my brass once at a reduced charge, is that something that is worth it? Also is there anything else that needs to be done to the brass in preparation? Any advice is greatly appreciated.
