The drama with such a wide range of possible "correct" bullet diameters is that any loading die that is purchased "off the shelf" is going to almost certainly do a poor job at getting a proper neck I.D.

Glad it's you and not me, DaveN! Too many projects here already. Still, it's really, really interesting.

I seem to be attracted to really interesting. A far cry from my major collection of M1 Garands. I haven't picked up one of those for quite a while now. They are still my 1st love.
Though I just picked up my K-31 today.

The rifle is back and now in one piece. The repair is still temporary as an 3/8 all thread is threaded through a inset threaded insert(don't know what else to call it) on one side of the sawed stock and into the same thing on the main part of the stock. I have ordered a gew98 cleaning rod and will have it threaded so it replaces the temporary all thread so as to have it looking like it should. I also ordered a sling and the parade sling swivel as to mount a sling with out disturbing the stickers is my goal here. I just want to be able to carry and shoot it in the near future.

Well, there is a simple trick that one can use to make a good estimate of the maximum neck size that will fit. Simply use a neck expander to a make an increasingly "blunderbuss" mouth to the neck, until you find that the cartridge case mouth is scraping in the chamber. Back off the expander a bit and repeat with another case, until you reach a condition where, if you mark the case mouth with a felt-tip pen, you do not get a bright line right round the mouth after chambering the cartridge. You need the felt pen trick, because it is too difficult to detect by feel alone. Measure that neck diameter and you know the absolute maximum neck diameter that will fit. Reduce that by another couple of thou, for safety and you have just about the maximum neck diameter that you can use when a bullet is seated. When you have acquired bullets of what seem to be the right diameter, repeat the test with a seated bullet in an empty case!

WARNING! As always, this kind of measurement places the responsibility entirely on YOU. This is not bench-rest equipment with bench-rest tolerances, so you must allow a looser fit than a bench-rest shooter would go for. If you use cases from a different manufacturer, you will have to make the test again!
