So I am using Starlight brass, and I'm getting into my first full length sizing with them. ( once fired now ) I have Lee 38/357 dies. Do I need to back the full length die out to compensate for the 357 (longer) case like with the other dies?
No adjustments are needed for the resizer die; just set it so it touches the shellholder at the top of the press stroke.
The seater needs to be adjusted higher when loading .357 Mag to compensate for the longer case.
I am using an RCBS Rockchucker, and yes a typo on the starlight.
