Toby you did ask me why I had a set of snap caps in this case? I did say that I used the same case for transporting other guns and left it at that, though now reading tour post I feel I should elaborate on my first answer.

Using a gun like the above at local clubs and shoots I find that the number of folks who are interested in why I shoot a hammer gun and the guns name and age does provoke that "do you mind if I can see what it is like to mount it" now not wish to to be a cantankerous old git I will always hand over the gun. Now a lot of these folks this is the first time they have been close to a gun that does not have barrels one on top of the other hammers that have to be cocked it is all new to them.Quite a number of years in my past I had a rather nice Gibbs hammer gun same can I hold scenario but this time quick as a flash one hammer cocked and trigger pulled, the hammers where beautiful fine and slim within a blink of an eye the gun was dry fired and the top half of the hammer went for an expensive flight of its own never to be found.
Today I keep this formula in mind when the can I hold it is said, "Expensive gun + the un knowledgeable + dry firing is a disaster waiting to happen. Because of this expensive lesson all my gun cases have snap caps on board. Though Toby I am very surprised you have never had this situation happen to your good self. So given the same situation I always put two snap caps in the gun "once bitten twice shy"

The only lessons in my life I truly did learn from where the ones I paid for!
