Opening day field test results. Boss bismuth #6 28 gauge out of a SBE3 with factory full choke. 6 birds 9 shots fired, 2 at my buddies cripples ( he was shooting steel). No cripples and ranges were 25-40 yards. Clean kills on every bird. Patterns great and seems to hit with awesome lethality. Big ducks to medium size, blacks and mallards to wigeon and woodies. I will keep shooting it out of this gun , I was very impressed with the performance. It isn't cheap but comparing it to the big name brands of bismuth and high end premium steel, the better performance mitigates the cost variance. Just my :z-two cents: Z
