I like it, great idea.

Part of the reason to file the flat is to get past the surface hardness and take a core reading.

Of all the reloading activities I've optimized, filing flats never entered my mind... it's really not that hard, or takes that long, nor do I do it that often.

Or just pour WFN boolits. He really bangs those moulds around.

Yeah he bangs them...made me cringe a bit! Did you see the smoke in the cavities? Can't get around doing proper deburring or else you'll have to smoke the heck out of them. Yuck!
