How should I store these primers safely at home?

Winchester #7 Large Pistol Primers belong in their original packaging, away from heat, sparks, and open flame. Primers are sensitive to impact and friction, so keep them in a cool, dry cabinet. The NSSF safety page offers guidance on storing reloading components.

Which cartridges typically use this primer size?
