What chokes do I use with steel, bismuth or tungsten alloy shot?
Steel Shot • As a general rule when switching from lead to steel shot you would use a choke with one full degree less constriction. • If you want a full pattern with steel use a modified choke. • If you want a modified pattern with steel use an improved cylinder choke. • If you want an improved cylinder pattern with steel use a cylinder or skeet choke. • Do not use any choke tighter than modified constriction with steel shot unless the choke is specifically marked for use with steel shot. Bismuth Shot • Use the same choke you would use with the appropriate size of lead shot. Tungsten Alloy Shot • There are several different alloys available. These can vary to a large degree in their level of hardness. When using factory chokes I suggest you use nothing tighter than full choke unless it is approved for tungsten shot. As a general rule most Trulock chokes are rated for Hevi Shot, Hevi 13, Federal Heavyweight and Winchester Hi Density tungsten alloys.
