O.a.l. for lee .358-158 swc in .357mag

[Castbill]

What is the right overall length for lee .358-158gr. swc in .357 mag with 4.5gr. of titegroup? Lee book says 1.610 . If you stay at 1.610, it leaves a ring out of the case. I don't want to seat to deep. Any input would help. Thanks, Castbill

Seat it to crimp in the crimp groove and don't worry about seating depth.

If you are using the tumble lube bullet use the book OAL and don't worry about the one groove being above the case. If your using the traditional lube boolit seat to the crimp groove, use starting data and work your way up.

I crimp them in the crimp groove.

New reloaders get too tangled up with the concept of OAL in a revolver.
If the cast bullet doesn't protrude from the end of the cylinder in your revolver, you're good to go. Don't assume that the book calls for a certain OAL and you MUST restrict yourself to that OAL.

A cartridge like a 9 mm Luger or a 380 Auto is another story entirely , the OAL on these rounds is more critical because of feeding and the possibility of reducing internal case capacity with " deep seating " of bullets, causing a dramatic spike in pressures.

Exactly. If you pick a mold cut ten years ago compared to one cut last month, they will vary dimensionally. The crimp groove could be higher or lower and the nose may be different. Lyman 429421 is a good example of that.
