B Frech,
Thanks for the hot glue tip.
Kcordell,
Thanks for the information it is similar to what I received today from RMC.
I went to Cody today and visited with Dave at RMC. Dave suggested that I ensure that the inside of the hulls are clean and he recommended wetting a rag with carburetor cleaner and wiping inside the hull mouth. He also suggested oversize overshot cards and recommended Ducco cemen (which I use). I have 11 shells in my case tumbler and when they are shiny and bright I will try Dave’s suggestion on half of the hulls and Bill’s hot glue tip on the other half.
