Thanks Daryl. Good to know.

I suppose that necessity drove me to solve for "x".............

This combo gun of mine sees lots of vault time and some field trips every fall, but it doesn't do much sporting clays

. Consequently my 2 3/4" cut downs will last me for a very long time. It's a lovely Pre war deeply engraved, gold game animal /bird inlay w/colour case hardening Kirsten lock 7x57R under 16 gauge 2.5". Very light, superbly balanced with nice lumber and in really nice condition, but I do use it to hunt chickens and whitetail hunt on occasion. All my hunting rifles and shot guns see field time, at least as much as I have time to give them, as it should be.
