I just finished loading up 25 rounds. Started at the lowest charge and went up in 0.2gr increments. Will do a total of (5) 5-shot groups. I have kind of low expectations. Something is up with the FCD. After seating the bullets, the overall lengths were pretty consistent. After crimping, i had substantial length variation. Not sure what's going on yet. I need to do some reading and research, then likely take the die apart.
