If you're conducting an inventory for potential future losses, such as theft or fire; I strongly recommend digital photographs.
Store those images someplace AWAY from the location of the items, such as in a bank safe deposit box, at an attorney’s office, at a trusted relative’s home, secured in “the cloud”, at a remote office or business you own, etc. If there is a loss, such as fire, you will not lose the records in the same event.
In addition to reloading equipment, photograph: firearms, jewelry, expensive electronics, high end tools and other valuables. Not only are expensive items prone to theft, but insurance companies will bicker about the value of a claim without some evidence.
When photographing firearms, at least three images are usually needed for a full record. An overall photo, a close up of the serial number and a close up of the make and model. The beauty of digital images is you know instantly if the image is adequate. If the image is blurry, delete it and do it over. Digital images cost almost nothing to make and are easily stored. That type of record is HIGHLY useful in later criminal investigations of theft and/or insurance claims.
Along with those images, ledger of values, and any appraisals, maintain a copy of any relevant insurance policy(s) - in a safe, remote location.
