Willie,
I thought I would bump this thread and see if anyone has any info for you.
I personally, do not. I have never made caps, but a did a little research on the topic a while back.
I know that there are capsules made for dry powder and others made for liquid.
I know that there are multiple sizes available also.
Unfortunately, that is the full wealth of my knowledge on the topic.
Hopefully someone in the know will chime in for you.
Good Luck,
WillieP
