Will Bismuth Loads Cycle Properly in Semi-Automatic Shotguns?

Cycle Issues with Bismuth Loads

Bismuth loads can cause issues with cycling in semi-automatic shotguns due to their heavier and bulkier properties. Bismuth shot is typically around 20-30% heavier than traditional lead shot, which can prevent the action from fully closing. This is because the heavier shot is not ejected from the chamber quickly enough, causing the bolt to bind and preventing the action from cycling.

Effective Solutions for Cycling Bismuth Loads

One effective solution is to use a shot size that is larger than typical loads, such as 1 1/8 oz or larger. This increases the volume of the shot column, allowing the action to cycle more smoothly. Additionally, using a load that has a higher velocity can also help to ensure proper cycling. Some loads that are specifically designed for semi-automatic shotguns and use bismuth or other non-toxic materials may also be a good option.

Tips for Reliability with Bismuth Loads

When shooting bismuth loads in a semi-automatic shotgun, it’s essential to keep the action clean and well-maintained. Regularly cleaning the chamber and bolt face can help to prevent the buildup of residue and debris that can cause cycling issues. Additionally, using a shotgun with a smooth-operating action and a reliable bolt can also help to ensure proper cycling with bismuth loads. It’s also worth noting that some shotgun models may be more suitable for bismuth loads than others, so it’s essential to research and test the specific load and shotgun combination before using it in the field.
