I thought I Was Anal!
.....for running ALL my loaded auto ammo through a case gage. Those that don't pass get plopped into the barrel of the intended gun.
.....for throwing all charges through a high quality power measure, weighing charges often, and then inspecting each case as it sits in the block with a bore light. Very easy to see squibs or double charges.
Now, I load on a progressive. It is manually indexed. Every case is looked at as it goes by to ensure it has powder in it. I watch to see (and feel) every primer that comes from the tube to the seater. Every round still gets case checked, same procedure.
I have caught squibs, double charges (overflow), primers seated upside down and sideways. Cases that have been dumped into the bin with no bullet in them (messy), cases that were not crimped.
These thing rarely happen and are easy to catch if you pay attention. The biggest problem are distractions! Wife, kids, dog, phone, getting another beer, etc. So far, after over 3 thousand rounds, no "others" have made it to the range. Just make sure that when you sit down at your bench, you can devote your full attention to loading with no distractions.
You probably could not wear your Sig out in your lifetime if you tried. But if you did, all the parts are factory or aftermarket replaceable with as good or better parts.
