Well, I hope you guys do better than I did yesterday!
I just posted results of yet another failure. It turns out that the nice flare I put on the copper Brenneke skirts was a bit narrow and sharp resulting in grabbing the hulls and tearing chunks out! Bad juju that!
I will try changing the flare to a cylindrical section if I can as that should eliminate the grabbing and as another test, I will use unflared tube and ball in a shotcup. So two more range reports to come.
I am depending on you guys for some successes at this point!
Cap'n Morgan and Chicken Thief ~ you guys both have good slug designs going here but the wad/skirt is the issue I have not yet solved so I hope you do.
