My pricing would be several years old, so probably irrelevant. Unlike rifle and pistols, there is NO pressure testing process for home hand loader in shotgun shells - you need to find a published load and use the exact same components - same brand of hull, same brand of wad, same primer, same weight and type of powder. I notice most recipes only list weight of shot load, so it seems the exact size of shot is not critical. So people do mix R-P, W-W and Fed brass to load a rifle cartridge, or interchange CCI, Fed or W-W primers - everything I read and was told says that a shot shell reloader can NOT mix and match - must use exact components - so actually spend a lot of time looking for recipes for the stuff you might already have on hand. Sometimes discover that one brand of hull is actually also used and sold under another brand name, so those two hulls (different brands, but same maker) seem to be interchangeable.
I used the Lyman Shot Shell Handbook to find a recipe. There are other published sources - BPI seems to have a lot - using mostly BPI brand wads, but not always. Then got a bunch of the specified hulls, then the primers, then the wads and the powder. I bought an MEC loading machine from now defunct WholeSale Sports - already set up for 28 gauge - with fuss and extra components can be re- configured for other gauges - I have never tried. The one change I made was to remove the fixed shot and powder bar, and replaced with a "universal" one - probably not needed - using my reloading scale I set the powder chamber to the recipe and the shot chamber to the recipe and have never changed it. Have never changed components either - I think only shot size was "changed" - #6, #7 1/2 and #8 have been used. Probably could have found or made appropriate fixed chambers.
Kind of misleading to read about "flexibility", etc. Sort of not what I found is needed. You will find a recipe. You will stock up on the specified components. And then you want to repeat exactly the same over and over. So once everything is set, I pretty much have had no reason to change anything. So, "fixed" (if I could get the correct one) is as good for me, as it turns out, as the "universal" is...
