Then I load five rounds of that powder charge, and five more at each increasing charge level, 0.5 grain increas per five-round group for standard cartridges, and at 1-grain steps for true magnums (not so-called "magnums" that usestadard capacity cases!).
I do similar, BUT I want to point out that since the poster doesn't say which cal. he is interested in loading for,we must remember that with the smaller cals. such as .17 Rem. or .204 ruger, a powder increase of .2 grains would be better because thepressures rise quicker in the small cases than they do in larger cases, 30 cal.for instance, where a .5 or even a 1 grain increase would be fine to use.
