I don't HAVE quirks! Everyone else does! My processes are totally logical and well thought out. Hah. Right.
Probably my biggest OCD-like quirk is record keeping. I have three ring binders that document every handload I've created since I started in the mid-80's. 1980's guys, not 1880's.
Next up is inventory control. A spreadsheet shows current stash of powder, primers, bullets and cases. Every lot of cases has a number and a log sheet. I can tell you how many times the lot was loaded, trimmed, annealed etc. Bullet inventory drove me nuts until I set up a bunch of numbered 50 call ammo cans. My inventory spreadsheet shows what bullets are in which can. It used to be that I'd buy more of what I didn't need and forget to buy what I needed.
I may be obsessive, but am I obsessive enough???
