Thread: Micrometer Seating Stems - A Primer

I’m no expert man and a lot of it is probably a bit of superstition or voodoo.

1-Anneal brass
2-Use the correct seating stem or modify one to fit your projectile
3-Use graphite powder
4-Ensure you can use callipers in a way that give consistent readings
5-Insert as many other steps into you brass prep regime as you feel necessary

More experienced people can talk to neck tension etc but it’s something I’ve been lucky enough not to need to reach my accuracy goals.

I recently stopped using my $90 Frankford Arsenal Digital Calipers in favour of some $120 Hornady Dial Calipers. Same rationale as favoring good balance beam scales over $100 digital scales. What a difference it makes. The reading is the reading no longer an approximation.
