I think I can get a .000g scale and weigh out the powder. I was going to cap up 30 Dbol/Drol/AI blends for a kickstart blend.

I don't think the weight of the cap matters if you want to weigh the entire thing at the end, I'd weigh the cap empty first then that plus the powder.

My best guess is the filler is to make the raws easier to work with if 50mg's is so small an moist maybe that it's a bitch to get in a cap. My guess.

I have found for other things though, the next time you go to the Dr. steal a few of those things off the wall that they use to put on the ends of the ear flashlights. Perfect funnel.....If you're doing them one at a time.
