Help on ID of tool/die

I’m selling out my loading equipment and this was in box with a primer swager. My computer chip is getting weak but I can’t remember what this is. Maybe part of something I never used. The main body is marked .311 and stem is marked 413 and relieved for spitzer bullet like a seater. Large bushing is press threads. Anybody know what this is or for?Attachment 280602

Lyman bushing for 7/8x14-to-310 threads. And a .311 bullet sizer and punch

Yea, What He said. That boolit sizer was made to use in the Tru-line Jr press. I think they made another press for that size die but I'm not sure on that.

2 black parts looks like drop tube and adapter to 7/8 threads for Lyman 55.
