I discovered this back in 2007 and talked to Patrick Ryan about it - the following year they put a warning in the catalogue about it - it is on the lower right hand corner of page 3 of the 2014 catalogue. Probably in the same place in the new one too.
Dear CatShooter
Some days I would like to shoot you with a dull bullet for some of your unfinished cryptic replies here.
For the sake of the people who do not have the 2014 catalog and page three of the new 2015 catalog is carbide pistol dies...................
Just when we thought you were going to ride to the rescue you crap all over the unicorn and slip off his back and ruin the ending of the story!
P.S. The Japanese have a name for a guy like you.......................a big plick!
This is on page seven of the newest catalog............ :
The easiest way to determine the proper diameter bushing,
is to measure the neck diameter of several loaded
or dummy cartridges with an accurate micrometer.
Subtract .001â€â€“.002†from the average neck diameter
and this diameter bushing will generally size case necks
to create the proper press fit for the bullet.
Note: If the neck wall thickness of your cases is on the
thin side of the SAAMI tolerance, your fired case necks
will measure considerably larger (.006-.010†larger)
than your loaded cartridges. Under these circumstances,
our tests have shown that a bushing .001“ larger may
give the desired results.
Another method is to measure the neck thickness with a
ball micrometer. Double the neck wall thickness and
add this number to the bullet diameter. The result is the
neck diameter of a loaded cartridge, and bushing size
can be determined as above.
After loading several cases, it’s a good idea to test the
neck’s grip on the bullet. The simplest method is to push
the bullet in a loaded cartridge against the edge of your
reloading bench with moderate hand pressure. The bullet
should not move easily in the case neck. If the bullet
pushes deeper in the case, select the next smaller bushing
and start again.
When using your bushing die, we have found that lubricating
case necks and installing the bushing numbers
down may improve results. Many reloaders like to
adjust the die to size 1/2 to 3/4 of the case neck. This
has been shown to improve accuracy in some instances.
