As a very long time hand loader of the .45 Colt cartridge I've often been frustrated by the fact that the old steel sizing dies leave a bulge towards the bottom of the case body and the carbide dies over size the case sometimes leaving an ugly ring. But I full size because I want all my cases to fit in all my various .45 Colts.
In recent years I've taken to using my old steel die again. It works very well but of course still leaves a bulge towards the bottom of the case.
Then in my minds eye I designed a carbide sizing die with two rings. The one at the bottom would size the case to SAAMI specs and the upper one would size the case down to hold the bullet, but only to the base of the bullet.
Redding beat me to it, or they read my mind, not sure which.

These dies are very expensive, but I AM going to put the money together somehow to buy one.
As far as I'm concerned this die would solve many little problems with the over generous .45 Colt chambers without leaving an unsightly bulge from under sizing, or a ring from over sizing the cases.
I'm gonna get one as soon as I can.
I just thought I'd let you guys know about this cos to be honest it's the first tool I've seen in years that really has me excited and drooling.
Now if just 10 of you guys would buy one cylinder bag each I could do it pretty quick.
