A Reloading tip so simple, it will only take a moment to talk about, and even less time to do.
A fair percentage of reloads that cause problems are the result of cartridges loaded with no powder, or a charge significantly different than planned.
When loading single stage, a moment with a flashlight looking down at the racked cases can assure the hand loader that every case has powder in it, and all the levels look roughly the same.
For those loading on a progressive press, a strong light positioned to aim directly into the charged case is a good idea, letting the operator glance in to see the charge in place before pulling the handle for the 45,876'th time.
Simple procedures, but priceless in terms of safety.
