full length sizing, or ...

[Opencountry]

I use Lyman dies to FL size my 45-70 Shiloh Sharps for gg shooting. Of all the FL sizing dies I have used the Lymans size the least amount, allowing a longer case life. My first FL die was an RCBS. It really squeezed the case down considerably when set to touch the shell holder.

In my bull-barreled 45 2 7/8" Shiloh I size only the last .10" of the case mouth with a Meacham neck die, just enough to hold the patched bullet. The rest of the case stays as fireformed. I anneal after each firing to ensure a good gas seal on the chamber wall, and to be sure the tension on the bullet is always the same with each bullet/case fit.
