OK so I am trying to find a new way to throw powder on my Lee load loadmaster. Auto disc pro works good for pistol but need something different for rifle. Tried the double disk kit and hate it. I know I can buy all kinds off lee or hornady measures but what I would like to do is use one of my spare Lyman 55 I all ready own. I have the 7/8 bushing but what are you're thoughts on a tight seal at the case neck. FYI I don't mind flipping the handle on the measure to charge. Any way to use something like the lee thru expanding die below to keep spillage to a minimum? Been charging into a cup and dumping through a funnel on the lee die. Just want to eliminate a step if possible
