I also shot 1,500 fps steel No. 1s and 1,350 fps bismuth 2s into gelatin, which bore out what most energy tables will tell you: At 30 yards, the two loads produce similar penetration. You can expect bismuth to perform very much like the next size up in steel. That’s not performance on a par with Hevi-Shot or Xtended Range Tungsten or TSS, which hit like much bigger steel pellets, but it’s better than steel, and it won’t hurt your gun barrel or break the bank. My Model 12 is going goose hunting this fall, and I bet a bunch of other old guns are too, and that’s reason enough to celebrate bismuth’s comeback.
