<< I would think the extra thickness would be
problematic as well. >>
Peter is correct. Think about it<G>; if the back
of each shell has oil on
it [and prolly NOT the same across the board ]
then the clearances ARE
changed to a 'closer' number.
"might" be OK, but then again ..............!!
TOO tight is not good !!
PS: DRY <G> !! And I seriously doubt one could
put enough oil on the back
side to make the shell 'spin' - they DO have tangs
