12 GA 2 3/4" Boss Unmuzzled Bismuth load, pheasant
After purchasing two boxes (20 rounds/box @ $35/box + $10 shipping and tax = $87) of the Boss Unmuzzled 12-gauge 2 ¾-inch 1 ¼-ounces of #4 Bismuth load online from Boss, I dissected and patterned these shot shells to assess their component consistency and patterning performance.
I cut open five shells, from the same lot number as the shells to be patterned, and the components (powder and shot) were weighed, counted, and measured for consistency.
Here are my findings from the dissections.

PATTERNS / BOSS UNMUZZLED BISMUTH LOAD
The pheasant load patterning was done with a Browning Citori 12-gauge w/ 28-inch barrels and using Briley flush Invector-plus IC (.011” constriction) and IM (.025” constriction) chokes. The listed constrictions are from a bore gauge.
The 30- and 40-yard (muzzle to target) pattern data is the result of hits registered in a 30-inch post-shot inscribed circle from five separate pattern shots.

So… How does the Boss Unmuzzled Bismuth load’s performance compare to some other lead and steel pheasant loads? Well, here are a few more of my pattern numbers using the same gun and chokes as above for comparison.
PATTERNS w/ Briley flush Invector-plus chokes
30 yards / IC choke / Fed. Game-Shok 2 ¾” 1 ¼ oz #5 lead (224 pellets) / pattern 173 (77%)
30 yards / IC choke / Reload (Unique) 2 ¾” 1 ¼ oz #5 lead (210 pellets) / pattern 177 (84%)
30 yards / IC choke / Rem. Sportsman 2 ¾” 1 1/8 oz #4 steel (218 pellets) / pattern 202 (93%)
30 yards / IC choke / Win. Xpert 2 ¾” 1 1/8 oz #3 steel (162 pellets) / pattern 132 (81%)
30 yards / IC choke / Rem. Sportsman 2 ¾” 1 1/8 oz #2 steel (139 pellets) / pattern 129 (93%)
40 yards / IM choke / Fed. Game-Shok 2 ¾” 1 ¼ oz #5 lead (224 pellets) / pattern 149 (67%)
40 yards / IM choke / Reload (Unique) 2 ¾” 1 ¼ oz #5 lead (210 pellets) / pattern 174 (83%)

40 yards / IM choke / Rem. Sportsman 2 ¾” 1 1/8 oz #2 steel (139 pellets) / pattern 114 (82%)
Now you can be the judge, good luck!
