I wanted to see and put on paper what a Spred-R disc did through my 28ga. Repro's FULL (.034 constriction) choke at 15 paces and compare that to the same load w/o a Spred-R disc.  So I loaded up a few shells with the Spred-R disc on top of the shot.  Yes, the disc is a somewhat snug and tight fit in the AA hull, but as Martha Stewart  would say "That's a good thing!"  I used my standard Sporting Clays load for comparison: 
 
* AA compression formed hull 
* W209 primer 
* 12.9gr Universal Clays  
* CB1075-28 wad 
* 3/4 oz. #8 magnum shot 
* 1200 FPS  
* 10,800 PSI* 
 
* It has been estimated that the addition of a Spred-R disc results in less than a 500 PSI increase in pressure. 
 
The first pic below is the pattern at 15 paces with the Spred-R disc.  It resulted in a 19" pattern spread.  The second pic is a same load, but w/o the disc.  This load resulted in only a 10" maximum spread at the same 15 paces.
