smiledr69 Posted June 29, 2014 Share Posted June 29, 2014 Just started reloading on Dillon 550 and have done a couple of hundred .223 rounds. All of a sudden I am getting a ring around the bullets after seating them where it looks like the die push into the bullet. Ideas on how to fix this?

Steve RA Posted June 29, 2014 Share Posted June 29, 2014 Are all the cases the same brand ?? If not, it is possible the case thickness is different and the ones with thicker metal will be harder to seat the bullet into as the outside diameter will be the same on all of them. Yes, the marks are from the seating die. Link to comment Share on other sites More sharing options...

Vanniek71 Posted June 29, 2014 Share Posted June 29, 2014 you may need to open up the bell on the case just slightly so there is less resistance when the bullet is seated.....or lube the cases a little more. Link to comment Share on other sites More sharing options...
Steve RA Posted June 29, 2014 Share Posted June 29, 2014 Another thing you might check would be whether or not there is a small amount of chamfer on the inside of the case mouths. Doesn't need much but should not be a square corner. Link to comment Share on other sites More sharing options...
newboy Posted June 30, 2014 Share Posted June 30, 2014 Use a proper fitting seating die. Link to comment Share on other sites More sharing options...
ToddKS Posted June 30, 2014 Share Posted June 30, 2014 Inspect the inside bearing surface of the seating die where it contacts the bullet. If the inside has machining marks then you need to polish those out with lapping compound. I have had to polish almost every seating die I own.

IHMSA15151 Posted June 30, 2014 Share Posted June 30, 2014 Sometimes there is a sharp edge on the seating die where it contacts the bullet. Polishing a slight radius on the inside edge of the seating die might help eliminate your mark. Link to comment Share on other sites More sharing options...
smiledr69 Posted June 30, 2014 Author Share Posted June 30, 2014 Further researches shown that this is not that unusual with the Dillon 223.. Strange thing is that I'm using Sierra 77 grain match King bullets with the same Lake City brass Link to comment Share on other sites More sharing options...
