Cholla Posted June 7, 2022 Share Posted June 7, 2022 Who offers bullet seating dies to match the Lyman Postell 457132? I have seated a few bullets and it looks like I am getting slight deforming of the nose. It seems pointless to takes all the precautions to make sure all my bullets are perfect and weight the same only to have the bullet damaged while seating.

Lucky R. K. Posted June 7, 2022 Share Posted June 7, 2022 I made a seating die that has a flat point and touches only the tip of the bullet. It will seat the bullet with no visible marks. Lucky Link to comment Share on other sites More sharing options...
Cholla Posted June 7, 2022 Author Share Posted June 7, 2022 Thanks. I have that now and it appear to be changing the profile, making it more squat. I have made my own custom seating die for another caliber using a generic die and JB Weld but I prefer something professional this time. I am using a bullet sized to .459 with a .458 neck expander as that is what I read in several places to use. Link to comment Share on other sites More sharing options...
Kid Rich Posted June 7, 2022 Share Posted June 7, 2022 If you are using BP try compressing it so you are NOT using the bullet to compress the powder or start using a harder alloy for your bullets. All of my 45/70-45/90 etc are compressed to the proper depth then the bullet is pushed in by my thumb and then crimped. kR Link to comment Share on other sites More sharing options...
Desert Pete SASS #42168 Posted June 7, 2022 Share Posted June 7, 2022 Pretty much what Kid Rich said. I throw a black powder charge through a drop tube, put a .030 card on top, run it through a compression die and thumb seat the bullet. Since the rounds are shot from a single shot, I don’t crimp but crimp, or no crimp, is a religious discussion. It works for me. Link to comment Share on other sites More sharing options...
The Original Lumpy Gritz Posted June 7, 2022 Share Posted June 7, 2022 How much neck tension are you using? Link to comment Share on other sites More sharing options...

Do not use the bullet to compress powder Link to comment Share on other sites More sharing options...

Wallaby Damned Posted June 8, 2022 Share Posted June 8, 2022 I’ll second or third the compression die for powder followed by hand seating the bullet. I only anneal after about 5-6 reloads; seems more critical when the die is actually working the brass. I’m shooting a Hepburn and can index my case (I use the “*” of the Starline brass head stamp in the 12 o’clock position so this may go out the window if you’re shooting a lever gun. Thumb pressure contact with the rifling provides the final “seat” if that makes sense. Link to comment Share on other sites More sharing options...
