Quick Answer
In warm weather, bismuth tungsten loads require more attention to prevent damage to the bullet and the shotgun barrel, as high temperatures can cause the bismuth to soften and lose its shape.
Temperature Sensitivity
When temperatures rise above 70°F (21°C), bismuth tungsten loads become increasingly susceptible to deformation and damage. This is because bismuth has a relatively low melting point, around 271°F (135°C). In extreme cases, the bismuth core may even melt and stick to the barrel, causing a clogged shotgun.
Handling and Storage
To mitigate these risks, it’s essential to handle and store bismuth tungsten loads with care in warm weather. Shooters should keep their ammunition in a cool, dry place, ideally in a shaded area or a climate-controlled storage container. Before loading, ensure your shotgun is properly cleaned and maintained, paying particular attention to the barrel and chamber.
Loading and Firing Techniques
When shooting in warm weather, it’s crucial to load your shotgun with care and attention to detail. Use a consistent loading technique to ensure the bismuth core is properly seated and aligned. When firing, avoid rapid follow-up shots, as this can cause excessive heat buildup in the barrel, potentially leading to damage or deformation of the bismuth core.
