I stopped tumbling when my old Lyman tumbler died last year. Unless the tumbler media was removed by wiping with a shop rag and mineral spirits, I would get a paste form with the sizing lube which wreaked havoc with my dies and shell holders. I finally said to self, "why are you tumbling when you have to wipe the cases anyway?" So, I stopped, and I have been very happy ever since. It's easier to manage my cases, I cut down on the processing time, I don't get media kernels in my slippers that hurt my old feet. But the best part, it's one less piece of equipment and consumables (media) I have to stock. Minimalist dream.

I am obsessed with my pursuit of simple, economical, and performance of target.
The only reason I clean primer pockets (every reloading) is to ensure a solid primer seat. I haven't tested or proven it to be necessary. It's just one of those things I do out of habit. It really isn't any big deal, so I do just it. Only big deal things get my attention, big deal meaning more expensive equipment or tedious processes.
The absolute best case lube, best being defined as cost effective and performance effective, I ever used is Imperial sizing wax. A tin lasts me about 4 to 5 years, and I size about a thousand rifle cases a year. While I never had a stuck case with One Shot, I found myself always running out of the stuff and there would always be some remaining in the can (i.e. waste) as the volume reduced. Best move I ever made was switching to Imperial.
For some reloading is a hobby and they enjoy it. That's fine but for me it is a pain in the ass. After 50+ years of doing it, it has long lost its allure - it a necessary chore to have a steady supply of consistent performance ammo. If I was Warren Buffet, I would buy a lifetime supply of single lot Federal Premium Ammo and be done with reloading. Sorry for the vent. I live alone and sometimes I need to vent to someone other than the walls which are tired of my venting.
