Ring Around the Bullet
Quote from Reloader on August 12, 2013, 12:40 amWhen I seat a 230gr. FMJ bullet on my SDB, I get a ring around the bullet about 1/3 down from the tip at the seating die. I have ensured I'm using the RN seating die, and I see no evidence of jacket shaving when I run rounds through Station 3, so I believe the flare is adequate. I'm using once fired brass. One of my friends told me that I was using the wrong seating die, but I don't believe that's the case. Could the copper plating on the bullet be soft enough that it's being deformed by the seating die, or is there a simpler solution, like lubricating the cases first?

You might verify that you have the RN seating stem installed, which is concave in profile. The SWC seat stem would be more likely to leave this described indent in the nose of the bullet.

The lead is really soft.
