Yes, it worked pretty good, I haven't done it since my post but if I was going to shot one of my 54r's in a comp I would. I don't roll my own for this caliber because I have a couple thousand rounds of surplus "went a little nuts buying spam cans". I know people say its not worth it but I don't see how +or- 1 1/2 to 2 grains can't have an effect on POI. The bullets are turds no doubt but having a consistent charge did tighten the group a bit. Plus you can play with seating depth.
