I use my digital caliper to measure how long the shot column is in the clear Winchester hull, I add the thickness of a 10 gauge nitro card to the measurement. I cut a piece of 10 gauge hull that length and glue in a nitro card in the bottom and presto a 8 gauge plastic shotcup. A 10 gauge hull has close dimensions to a 8 gauge sp8 wad from what I can see, you get a shotcup that fully encapsulates the shot as well. They patterned too tight at 40 yards, I havnt had time to make more but if I remember I will before this weekend and test at 60 yards.
I got my roll crimper in today from Reloaders Network, I decided to test in on the Winchesters and paper hulls. I got to dig out my imperial wax as this roll crimper doesnt like the same dry lube I use on the BPI one. Not bad for a first run though I think.
