Re: Pistol cases tumbling/decapping procedures
Vote: Tumble till shiny and reload (no other case prep, no trimming, etc.) via progressive presses (DP 1050, Super 1050, 650).
I sort my cases and watch for cracks/splits (I can find a split case by picking up a dozen in my hand and listening as I shake --you can hear a different tone if there is a cracked/split case).
Primer pocket uniforming for pistol? No way (imho).
I typically get 10 firings or so out of my .38 superComp and .45 cases; slightly less for .40.
As a USPSA/IPSC shooter that has reloaded hundreds of thousands of .38 supers, .40, & .45, I can honestly say that I have never uniformed a pistol primer pocket. Never had any issues seating a primer (once press is set up correctly). I don't know any other hardcore pistol competitors who do either. In these sports, it's all about the range time, dry firing, "reloading is a necessary evil", etc. -- squeezing the last iota of accuracy out of a reload is not a top priority. That being said, I use inherently accurate projectiles (MontanaGold and/or Hornady TAP) that group under 1-1.5" at 25 yds as long as my barrel isn't toast.
Have I ever had a high primer? Sure maybe one out of every thousand or so rounds loaded. But, I look for those as I am putting the rounds into my 100/50 round boxes. If there's any question, a high one gets tossed.
LR Rifle? That's a different story entirely...
