Can You Shoot Tungsten Through a Lead-Only Choke? The Risks and Realities
The short answer is: you shouldn't. While it might work sometimes, shooting tungsten shot through a choke tube designed only for lead shot is risky and can lead to several problems, potentially damaging your firearm and compromising your safety.
Here's a breakdown of why:
Understanding Choke Tubes and Shot Types
Choke tubes are designed to constrict the shot pattern as it leaves the barrel, influencing shot density and range. Lead shot, being relatively soft and malleable, deforms slightly as it passes through the choke, adapting to its constricted shape. Tungsten, however, is significantly harder and denser than lead.
The Problems with Using Tungsten in Lead-Only Chokes
-
Increased Pressure: Tungsten's higher density means a given weight of tungsten shot occupies less volume than the same weight of lead shot. This denser shot column can create significantly higher pressures inside the barrel as it passes through the choke. A choke designed for lead shot may not be able to safely handle these higher pressures, risking damage to the barrel, choke tube, or even the firearm itself.
-
Choke Tube Obstruction: The hardness of tungsten can cause it to damage or even become lodged in a lead-only choke. The tighter constriction of the choke increases the likelihood of this occurring. A jammed choke tube is extremely dangerous and requires professional intervention to fix.
-
Inconsistent Shot Patterns: Even if the choke doesn't become damaged or obstructed, the harder nature of tungsten can lead to unpredictable shot patterns. The shot may not deform correctly, leading to inconsistent spread and decreased accuracy. This can significantly reduce your effectiveness in hunting or target shooting.
-
Potential for Barrel Damage: The increased pressure and potential for deformation can, over time, damage the barrel of your shotgun. This damage may not be immediately apparent but could weaken the barrel and eventually lead to dangerous failure.
What to Do Instead
If you want to use tungsten shot, ensure you are using a choke tube specifically designed for steel or tungsten shot. These chokes are manufactured with materials and dimensions that can handle the increased pressures and hardness of these denser shot types. Using the correct choke tube is crucial for safety and optimal performance. Check your shotgun's manufacturer's instructions and recommendations regarding appropriate shot types and choke tubes.
Conclusion
While the temptation to use tungsten shot in a lead-only choke might exist due to the advantages of tungsten's density and range, the risks involved far outweigh any potential benefits. Protecting your firearm and ensuring your safety should always be the top priority. Always consult your firearm's manual and use appropriate ammunition and choke tubes for safe and effective shooting.
