10 Gauge Boss Bismuth Duck Loads Pattern Test (Hand Loads)

#Mighty10gaClan

Well, being who I am, I have to tinker, and the excuse to create light for bore 10ga Duck loads was the perfect mini-project for me.

Using load data from Ballistic Products Inc. for ITX-10 shot pellets in “The Mighty 10” load manual, I have assembled reliable and deadly duck-getting hunting loads that are sure to be just enough medicine for ducks at 20 to 50 yards, and Geese under 45 yards. The Boss Bismuth was robbed from 12ga hulls, however Boss does offer at times the opportunity to purchase shot if an over-run is available.
