I posted a useful mod (at AR15.com) to control the press's primer feed a year ago. It works fine, but I found a faster, easier to build, and better way. (Mod 1 in the Link at the bottom of this post.)
Besides that, (See Mod 2) I found a simple way to stop the primer rod action that raises a primer in a strip, unintentionally, just enough to jam it. Which can happen when you forget to remove a strip, or don't wish to, during press operations on pre-primed cases.
A fact of life when using strips, is that the bottom of each primer in each strip does have to be flush with the strip surface before you insert the strip, or it can hang up in the feed mechanism. (The fix, when it does happen, is simply to push the errant primer back down...I use a hex wrench sized to just fit through the primer hole in the shell plate.)
As normal operating procedure, most of us Pro 2000 users place a bunch of strips on the bench surface and rub or roll something over them for insurance against a high primer, BEFORE the strips are inserted into the press. (I use a 5" wide laminate roller I bought at Lowes). If you make sure the primers in each strip are flat, then the only other time strip hang-ups can happen, is when you leave a strip full of primers in the press during press operations on pre-primed brass. (most often a onezy, stopped mid-cycle due to a powder drop problem, or maybe a few you had to pull bullets from and recycle.)
Anyway a Pro 200 uses a 3 stroke operation: 1. Down stroke indexes the primer strip and raises the shell plate, inserting cases into the dies. 2. Up stroke lowers the shell holder, and at the bottom indexes the shellplate. 3. Forward stroke, primes a case, by lowering the shell plate beyond indexing it, lowering it over the primer rod, raising it and the primer into the case.
The object of Mod 2 is to lock out that 3rd stroke. Stopping the shell plate from lowering below the point shell plate indexing occurs.
Here's the link to the mods. If you can use them, great.
