I have a big problem with pasting 2,5" shells, because after pasting 5 layers they are still too small for my mortar. The 2,5" hemis I bought are 54mm in outer diameter and my 2,5" mortar has 64mm inner diameter. After pasting the 5 layers the shell is still only about 58mm in diameter, so the shell has too much tolerance in the mortar, about 6mm. I read 2mm tolerance for this caliber is normal, and it sounds much more reasonable to me than 6mm. But pasting until the shell has only 2mm tolerance would mean 10 layers for a 2,5" shell? Do I use too thin gumtape oder should I paste more layers?
Hope you can help me
