Don't shoot steel in your old 37. Get Bismuth or Tungsten.


Moody is correct, but left out one key point. Do NOT use tungsten-iron (too hard for your barrel), but it's OK to use Kent Tungsten Matrix, or the old Federal Tungsten Polymer (if you can find it). There is also the new Nice Shot that is friendly to older guns, but not widely available except from a few big operations. Avoid Hevi Shot and Remington HD.
