I recently dissected and patterned these low-cost factory shotshell loads to assess their component consistency, quality, and pattern performance from a full choke at 40 yards.
Powder and shot data were obtained by cutting open five shells from the same box as the shells to be patterned and counting and weighing the components.
Patterning was done with a 12-gauge Browning Citori having 28-inch Invector-plus barrels and using a Briley flush full choke measuring .036-inch constriction from a bore gauge. The 40-yard (muzzle to target) pattern data is the result of hits registered in a 30-inch post-shot scribed circle from ten separate pattern shots.
