New 8ga recipe with Gualandi wad
 

I developed this load to minimize leading. I call it a reverse stack load, very simple.
8ga Winchester Industrial 3 1/2" long
WW 209
22.7gr Clays
8ga .125 card ward over the powder, followed by 1/2" 8ga fiber wad, followed by Gualandi 8ga wad.
1 1/2oz #71/2 lead
6 fold crimp.
Average pressure: 7066psi
Average Velocity: 1163fps

I shot a bunch of these loads today and was very happy, no leading issue at all. It does make more confetti because the fiber wad is not contained by the plastic wad.

I’d like that wad a lot more if the shot cup were a bit deeper !

Me too. But loading the way I do in this load results in about the same amount of shot being contained in the plastic cup as the sp-10 with fillers added to the base.

The confetti is just like a ticker-tape parade for a conquering hero!! Just sayin.

I have a couple of loads that make confetti, kinda fun, makes the guys howl in the duck blind! Bio friendly as well. Found lots of plastic hulls in the mud at the end of the season when my rice farmer drains the fields and we pull the blinds out. The pump and auto loader guys spray them everywhere and some have sunk when we pick up at the end of each hunt. Never found any card pieces end of season even though tiny pieces covered the water in front of the blind on a good morning.
