Also, since we're getting into the area of inspecting cases during the reloading process, someone on another site recommended getting a otoscope for inspecting bottleneck cases - particularly bottleneck cases under 30 caliber.
I got one from Amazon:
It has come in very handly. It makes it easy to see the occasional piece of debris inside the case. I have occasionally been able to see the shadow formed by the "valley" of the thinning case wall near the head before the tell-tale ring appears on the outside of the case.
I won't say it's the best $7 you'll ever spend, but I doubt you'll suffer from any buyer's remorse.
