What is a reasonable price to you?

RIO Bismuth can be bought for under $2/shell.

I load a light load of ITX shot 7/8 oz of #6 for my 12's and it does great work on ducks and geese, but I tend to wait for good shots. I'd rather shoot a few ducks with my old hammer double that have to hunt with a modern pump or SA. It just makes a hunt that much more enjoyable.

My ITX loads run about $1.35/round


After the first shot the rest are just noise.
