I'm experimenting with black powder in my 44-40 and want to try 26gns of 2fg with Semolina (cow) filler.
Once all cases are charged I hold the side of the loading block against my tumbler to vibrate the powder down.
Here's my rookie question:
Do I need to compress the powder prior to adding the filler or can I just compress the filler down onto the powder about 1/16" using the bullet?
