Like MikePal I try to be organized with my powder loads. I use plastic powder vials that are translucent so I can see the level of powder in each vial. My first vial is double checked with an electronic scale. This then becomes my comparison vial or as Mike would say go-no go gauge. All my load vials are then placed in a shotshell box in a specific order with a table chart added identifying what each row holds.
As I use each vial it then is returned to the shotshell box inverted to keep a better count of loads used.
Another aid I use is the old plastic boxes that Hornady originally supplied their 250SST bullet and sabot combination. Utilizing these boxes keeps the range bench uncluttered and allows monitoring shots I’ve taken with a quick count that should match.

There was one incident where the count didn’t match and had me concerned. One time I pulled a vial and set it down to engage in a chit-chat. When I returned to continue shooting, I did my witness mark check and the bore was empty. Quick head count of vials and bullets didn’t match being 1-vial short. Oh crap and wasn’t going to do any shooting until that vial was found. It turned out the vial had fallen over and rolled just out of sight. Sigh of relief when the vial was found and the numbers now matched up. I attribute this to short-term memory loss, chuckle.
Guess what I’m expressing is that my comfort range is dependent on detailed awareness at the bench. At any given time should I feel uncomfortable at the range I stop and find out the source of the discomfort. The last thing I want is a screwup that could be costly.
