Old Lyman Lubricator #450

Need to size some oversize bullets. Then measure after sizing. Harder alloys, with antimony, will spring back more after sizing. A .452" marked die, can spring back .001" to .453"
Or maybe pin gauges?
My RCBS vernier caliber can get close, measuring the inside of the die. An .008" difference should be easy to see.

If its a .452" die, opened to .460" a new center plug will be needed. Lube will flow to the top.

bottom says 452
Dies are easy to enlarge a few thousands, but not .008" Center plug becomes to small.

I been casting, using a Lyman 450, since 1970s.
 
Clean it up and measure it. Caliper precision should be good enough to tell the difference.

If that is bullet lube on it, then it has been used. If it is just packing grease then it is probably NIB.

In the old days you could order special sizes. If that was the case, Lyman would use a .452 body to ream out and then fit a custom pin.

Yes, RCBS and Lyman dies are interchangeable.
