This is my first go at loading shotgun ammo myself. I really couldn’t find much for pattern testing so I figured I’d post some results.
Here is the second try using a quad pin roller...
The first try was the hull on the left. I pushed down to hard when the roller was still cold. I even rolled the ones I hot glued in place. It made a mess in my roller but was easy enough to clean out. The above groups at 40 and 50 yards were shot with roll crimps.
Once I get the correct powder I’ll be rolling some 3.5” for my browning gold.
