SNAP CAPS STAY IN THE HOUSE - safer for me and those around me.

This is good sense. I only use my snap caps when checking the gun over - then take them out. I store my guns cocked, and after many years (some over 100 years), no problems with tired springs.
The only tired spring I have had was one lock only (off a sidelock s/s) made in the 1980s. I suspect a case of poor material/heat treatment there.
