We have enough topics... what we need are good threads!
Recording of information: I learned over my years in this gig to keep a log of EVERY THING! It helps greatly to keep from repeating mistakes. Many times, you'll look at a caliber or a bullet and get a certain idea. You may then try something. You HAVE to note the result. If you don't, you'll eventually repeat it. You may even get half way through it and say, "hey, haven't I already done this?"
On the box that the ammo sits in, I note the caliber, the bullet maker, the style and weight of bullet, the powder brand, the charge weight, and the COAL. I also list how many are in that box, and the date. That's it for the ammo box.
I tend not to note what brass I used or what primer I used, simply because I try to keep a stock of only one kind of each primer per size and I don't make much distinction with regards to brass.
In my database (excel spreadsheet), however, I keep a single page with a flat log, whether it's ammo produced or a range trip with results of some ammo, or a purchase or whatever. That's the log.
Beyond that, each caliber has a page of it's own, and the top grouping of loads listed are ones that I have tried and I keep the source of my data, the results of my shooting, and any techniques or quirks I noticed at the bench or at the firing line.
The second grouping of loads are "recipes" that I intend to, or might try. Duly noted that I have never actually range tested them. I move those loads line by line to the top grouping when I have tried them.
And if the load was AWFUL, for any reason, that's duly noted as well. I even go as far as to use strikethrough text, to make sure I don't accidentally make the load again if it's lousy.
For me, keeping every relevant piece of info is key.
