Actually Rusty, I'm talking 7 grains of Kapok getting spit out! I was using 2 grs. but followed you guys advice and compressed as much as I could get in the case. Improved groups also.

I have not seen any sign of the Kapok smoldering or burning when it is shot out normally. In fact I have never found any charred or burned kapok residue from any test when the primer and powder ignited normally. I only saw evidence of the burning from the misfires and when I did the primer test.

Here's a picture of one hang fires with RL15.

Cotton ball on the other had burn like crazy and stay together.

I just fear that the fillers that stay together slug up. Not good!

Just in case you don't understand what I mean by slug up. Here is a Pufflon slug from a misfire with RL-15.

Here is the slug and powder dug out. Keep in mind this slug was made from just a standard pistol primer. (Using CBC brass)
