thanks.
don't think a blackpowder will ever be on the radar for confiscation.
Berkey filter is best. you can avoid the Berkey cost/unavailability with just the filter and drilling out a large pot..
I have my eye on another A5 Browning. Gave my 20 to one of my daughters and think a 12 may be good to try. hard to beat a twenty for all around, though.
