Ok, I cast up a bunch of 00 buckshot with a Lee mold (un-graphited at this point for testing). I tested it out using Fiocchi hulls and primers, Red Dot powder, and Win AA12 wads. I trimmed the petals off the AA12 wads so I can stack the buckshot (9 pellet) inside the hull, and used no buffer. Results are ok, similar to Wolf 00 buckshot pattern.
I also disassembled a Remington 9 pellet 00 round to see what they were using as a wad. Inside I found a taller wad/shot cup combo with thinner petals so the 00 can still be stacked in 3's. I've been scouring the internet for such a wad and can't seem to find anything. Anyone have any suggestions on getting 9 pellets of 00 buckshot into a trap wad?
The reason I ask is I'm wanting to add some buffer to 9 pellet loads for tighter groups and I'm pretty sure you don't want to overfill a shot cup with buffer because it can slide down between the wad gas seal and get into the powder.
Any suggestions?
