I found a source for the Winchester 8-gauge kiln ammunition. These things are huge!
If interested PM me.

All ways wanted one of the cartidge guns, the best I can do is my muzzle loader in 8 bore, it will get ya every once in a while

I got the ones I built mentioned in 12GA FH thread.
I get 8ga kiln cases,rework the belt step for my chamber.
And then load them. We can't use the loaded factory
kiln cases as they are too dangerous with too
fast of a powder relative to slug weight.
8ga bird hunting guys in UK also do the same,
with their old factory made guns, and that is
where I got the idea from.Ed
