the next lower amount is .6 to.7 gr less.
Try the adjustable charge bar, it is the only one I use for pistol loads. It takes some getting use to to set it, very fine adjustment to get just the load you want, but once set it stays right at your setting for powder. I have been using it for 6 years now so I can dial it in without much problem. Some days are better than others, it takes patience but works.
I guess not everone's cup of tea.
