I remember ready a while back, somewhere, that there is a powder you can add to chalk to keep it from clumping and make it "poof" a little more upon impact.

Like a dumbass I didnt take good notes. So now my M79 is here and I am getting ready to make magic.

Can anyone help me out?

Cab-o-sil.

It’s airfloat so use in a breeze free environment. Mask and gloves.

You can mix it with OC powder as well.

All OC is, is hot pepper… get the highest scoville unit pepper powder you can find. That’s OC powder. Got mine off Amazon years ago.

You can also get (nearly) pure capsaicin or PAVA power off Ebay.

That sounds like the same stuff I use for fly fishing - helps dry flies float. That reminds me I should break out the rods; it has been too long.

Any suggestions?

Guess I will try 10:1 chalk to cabosil by volume unless anyone knows different.

....why? There's really no point using it with chalk. For OC/CS, sure. Some folks prefer starch based "Holi" powder instead of chalk. I have done both, but never really noticed a difference.

If you really want the chalk to be seen, I'd recommend "loose change" projos with a chalk payload.
