A few years ago I experimented with different loads in a few shotguns and fianally found a really great load of 000. It patterned all 10 pellets in about a pie plate at 35 yards. I thought wow, finally. Then I had a thought, why not just use a slug? Sometimes I think the advantage of buck shot is not to get a really small pattern. Too small and it becomes diminishing returns, obviously vis versa also. I get it, that in some areas you have to use buckshot no matter what.
