I have just set my Dillion 550B up for 115 grain 9mm plated bullets. I took one apart to check the crimping I had applied and found the bullet had a slight ring around it. I have included two photos of the removed bullet and a finished one to show the amount of crimping I applied. When I took this one apart, it separated with the first strike of the plastic hammer tool, suggesting that it wasn't over crimped. I did however see the slight indentation ring. The finished bullet doesn't appear to have the edge of the case crimped anymore that what was necessary to remove the bell. Does this appear to be properly crimped? Any constructive suggestions would be appreciated! Thanks, Steve Wanna kill these ads? We can help!
