Keith,
Good morning.
Funny you say that. After my initial trial moving a tube filled with shot under the barrels, I filled the cavity with #9 shot and thought about tamping it at intervals. I could actually get 7oz of #9 in the channel! Then the tungsten idea came to me, but I too think Kutter coming up with the ceroasafe idea trumps all. smile What an awesome wealth of information here.

Thank again everyone.
Best,
Bill
