Anyone have a method of ensuring powder doesn't get hung up in the powder drop on the 550 when doing 5.56? Using 4198 and 99% of the time it seems I don't have a problem but when it does hang up and then falls all over the place when I move to the next station its a pain. Saw on Dillons site one forum message suggested putting a vibration device that was foot operated and use it during the drop. Wouldn't know where to get something like that so wondering if anyone else has to deal with this.
