Do I start ladder testing for my 260AI at max 260 loads of H4831SC?
Also I bought magnum primers because I predator hunt in the cold usually 15degrees or colder here in Marquette. Anyway I bought the primers because I thought I read somewhere that use magnum primers in extreme cold, large powder chargers, and ball powder. So can I find my winter load of H4831SC and magnum primers in fire formed cases near the top of the 260 Data?
thanks for all the help. Good luck this hunting season It just started for me here in Michigan.
