This is a few photos of how I modified my Lyman 55 BP measure. I could never tell how much powder was in it. I took the idea from my RCBS. Just drill a 1/4 in hole in the center of the top cap. Cut a piece of 1/4 wooden dowel rod and use JB weld to mount a fender washer to the end of dowel. It's not sloppy work on the fender washer but done on purpose to add weight so that it will follow the powder. I also marked the dead bottom line in red so that a quick glance would give me a reading. The very top of the dowell can be marked with the correct powder lines and used as a depth guage for bullet seating.
