Spreader choke????

[Old Guard Dog]

Looking through the Mossburg spec sheets, there is a special purpose mod 500 in .410 with an 18 1/2" barrel and a "spreader choke". Most short barrels for HD are always cylinder bore. What is a "spreader choke"?

More open than cyl bore. Larger pattern at closer distance.

AKA "negative" choke- several companies offer negative choke tubes.
