O.K. I think I'm having a "senior moment" here and just need a quick explanation of the NOE expander plugs.
I know "what" they are and how they work in the Lee universal expander (flaring) die - but I can't find an explanation on the site as far as what the listing indicates or which to order for what size boolit.
Example - In the Rifle expander plug section . . . .
one that is listed is the ".311 X .307 Exp. Plug". What does the first number indicate and what does the second number indicate?
All I use is cast. As an example, I am getting started in 30-30 but with the molds I have, I think one will drop at .311 but the other at .309. I'd like to load "as dropped or "as sized" - still playing with them so it could be that they would end up being sized .309, .310 or .311.
If I were going to use a boolit sized at .309 (plain based or gas checked) . . . which expander plug would I want to order to insure correct neck tension?
I may have missed an explanation on Al's site but I couldn't find one when I looked several times. I have not seen one of his expanding plugs - are they the same profile as a Lyman "stepped" M die expander or a different profile?
Thanks in advance if someone can explain - greatly appreciated. At the price they are, I figured I would pick up several different sizes to have on hand for various boolit diameters for the 30-30 and also for my 8mm Mauser. I have several different boolits I use for that - two at .323 and one at .325.
Thanks!
