"The proper and safest way to clean and store a firearm is to first make sure that there is no ammunition in any part of the firearm. Take it to a gun smith to have it properly cleaned and when you pick it up, they can sell you a trigger lock for your gun. Always store your gun in a lock box."
For a home owner the best way to store ammunition is inside a gun safe. Preferably in the climate controlled living area.
Only buy ammunition that matches what is printed on your barrel. There are a few exceptions but that is the general rule.

An ammunition store is commonly referred to as an "armory" or "ammunition depot." These facilities are designed for the storage, security, and distribution of munitions and related materials. In civilian contexts, such stores may also be called "gun shops" or "firearms dealers" when they sell ammunition alongside firearms and accessories.
