So, I was running a batch of .223 through my Dillon Super Swage in order to get rid of all the military primer crimps.........and I noticed something. There's a little, spring loaded bar under the case that you adjust in order to keep the cartridge base at a uniform height. You put the first case in and move the lever forward to crimp the pocket, then loosen the little bar so that it rises under the case, then lock it in that position. From that point on the cases are all at the correct height for the ram and anvil to do their work. However......
The cases can still move to the side somewhat and I find myself using my thumb to center them horizontally before swaging. If you don't pay attention it's easy to hit the pocket edge and damage it. My idea is simple......form a shallow "v" notch in the top of that bar and, after initial setup, the cases will be aligned both horizontally and vertically.
I actually called Dillon and asked to speak to one of their designers, but after two unanswered calls I gave up. Such a simple change would make the swager even quicker to use and I think the idea has merit. I'll be disassembling mine tonight and putting a notch in it.
