New to loading dasher. Just had a rifle built and was starting to work up a load. Noticed the bullets was sticking in the seating stem on the widden seater. Seating 109 hybrids. I’ve been reading and understand it’s a somewhat common issue. I realize widden makes custom stems. Problem is I don’t have the time to wait on one. I seen where people say to use 600 grit sandpaper or lapping compound to polish it to fix the issue. Any personal experience or advice would be greatly appreciated
