With respect to others,
I have to second reading a good book on reloading.
RCBS has a good book, with reloading information added,
The best reference I've found is the NRA (Not brand specific) book, but I don't know if it's in print anymore.
Amazon or Ebay will probably turn up a copy if it's out of print.
Secondly,
I shoot black powder Sharps, and you picked a case with a TON of surface area that contacts the sizer die!
It's a LARGE DIAMETER, TAPERED CASE!
It's a MOTHER to get resized without significant force on the handle of the reloader since the ENTIRE case is being tapered back down to factory size ALL AT THE SAME TIME.
All that surface area is in contact with the die at all times when resizing, so you MUST have a good lube...
The lube actually keeps a 'Hydraulic' layer between case and die,
And when you use enough, the cases will still seem to 'Stick' at the top of the stroke.
This is because you hesitate at the top, reverse direction,
And the lube gets a chance to migrate out of the case to die contact,
Leaving the case in DIRECT contact with the die.
I find it MUCH easier to IMMEDIATELY withdraw the case when it hits the top of the stroke.
If you let it sit at the top, more lube migrates out, and the case will be harder to get moving again...
You will 'Hydraulic' some cases,
You will 'Stick' some cases... Until you find out EXACTLY how much lube to use.
This is a case of use RCBS case lube on a lube pad,
Instead of spraying the cases lightly and running them...
The spray on 'One Shot' lube never worked for my long, tapered cases,
I know it's 'Slower' to hand lube on a pad,
But it takes more time to beat a stuck case out of the dies than to hand lube,
And when you hand lube on a pad, you can control EXACTLY how much lube the cases get.
