Ive never come across anything that was too generously chambered or the bore was overly big. Ive dealt more with tight chambers and short throats. There is one mosin M38 that I do need to slug the bore on because I’m curious about it.

Ive used the lee collet neck sizers, bushing dies and standard neck and FL dies. Ive never had any custom die or die parts made.

Bushing dies do work better with neck turned brass, it is recommended to use the expander ball with them if your necks are not turned. The lee collet die does well either way.

Most of my plain Jane dies give me .003 neck tension, some a little more, some a little less. For most applications I find that is adequate.
