Re: H4350 vs h4350 EXT... Different data /powder?
My first choice of reloading data is the manufacturer of the bullet being used . My second choice is the powder manufacturers data . If I have neither I will cross reference the powder in 3 manuals and average a starting load , and work up from there . Never reload anything with out cross referencing at least 2 manuals , this avoids using bogus info , due to a misprint in one manual . It's standard operational procedure among most smart reloaders !
