The bullet seater plug that comes with the die set is as close to generic as Lee can make it. If you find that the bullet seater plug deforms the nose of the bullet you are trying to seat, Lee can make a custom bullet seater plug to fit your bullet. For this they would need a sample bullet, payment of $13.00 ($8.00 + $5.00 S/H). Current lead time is two days to one week.
Many times, you can fix this yourself through the use of a drill press. Secure the seater plug under a 3/32" bit and drill further into it. The distance should never be increased by more than 1/4". If this does not solve the issue, we recommend sending it to Lee Precision.
