Yeah, George, I hear ya..always used 4s when rabbit hunting with a .410 just for that reason (couldn't get anything bigger and didn't handload .410s then). And the fewer, larger shot are much easier to track and and find in the meat. But I wonder if they REALLY sold many .410 1s....

Now that I think of it, I'm not sure I've ever SEEN a #1 shot, loaded or not!
