every powder has a different density I can fit almost a gram of vat attack in a '00' sized cap, but only get 550 mg of gte in the same cap...
search the threads, there is one that has pictures with each step of the process. silentbob was the one who posted it... if it helps.
some powders are very messy and some are easy to cap it depends on which one you are trying to cap. I do it at my dining room table with some newspaper underneath my capping it.
ps... if you hook me up with a free tub of orange cycle support. I'll really really promise to do almost, but not really, anything!
