Thanks to you both

handloader1,
Since I am going only from the 30/06 brass to the 8mm opening (.308 to .323 or a bit more for bullet seating) do you think I need to have a mid-step to incrementally open up the neck? Is it to abrupt to go straight to the 8mm expander ball directly from the 30/06 brass? And thanks for the tip of the Imperial Sizing Wax...

Ridge Runner,
The cornmeal you mention is of course cornmeal tumbling media, right? And the twisted up worm of paper towel just needs to be big enough to plug up the mouth so the powder and corn meal doesn't fall out right? Or should the paper towel plug be really jammed in extremely tight? And lastly, pointing the gun down at a 45 degree angle should be ample to keep the burnt cornmeal out of the chamber, eh?

Again, thanks to you both for the tips, ... and anyone else please throw your tips and/or experience my way.

John
