First Bullets
I finally got my Blackmon dies and have made my first few 6MM bullets. I have a couple of questions about my results.
1) What final diameter (pressure ring at the base and the area between the base and where the ogive starts) should I be expecting? 2) When I remove the jacket/core from the core seating die, I see a mark at the base of the jacket. It starts at the base and spirals up the jacket about 1/8", and makes a bit more than one full revolution around the jacket. Any idea what can be causing this mark, and how can I get rid of it? Thanks John |

I have not heard the concern about using the "breakover part of the press". That is how I currently have the die / press set up. I'll re-adjust it this afternoon and give this advice a try (to see if it has any effect on the marks on the bullets). Thanks

John you want the cores seated firmly but without bleed by the punch. On 20 caliber bullets, since the jackets are formed from .224" jackets you have to seat them to form out the base of the jackets. .243" jackets that should not be an issue.

john, glad you have got your die's. normal dia's. pressure ring should be about .0002 larger than bearing surface. not sure about other mark picture would help alot. also you can control diameters with type and amount of lube used. george

I've got a few pictures. Working on figuring out how to attach them. Hope to have a couple pictures posted soon. As for the pressure ring, I am getting about .0004 larger than the bearing surface. How can I control this with the lube? John |

Bullet Pictures - with strange marks
OK, this is obviously beyond me. Can anyone tell me how I can attach pictures (that I have on my computer) onto a post on this site? Thanks
