I have all the parts ordered for a 338 Norma build, and am starting to collect reloading components. Is there anyone out there that can give me some suggestions on powders that should work? ( other than RL22 ) It would also be helpful if someone already shooting this round had some good starting loads. I will be shooting 300gr SMK until the new Bergers come out. Would Retumbo & H1000, and some of the other powders the 338 Lapua and Edge shooters use be a good place to start?
