The Lee 303 British Collet necksizing die uses a steel collet to squeeze fired cases to a precision mandrel, creating a precisely aligned case neck while reducing run out. No case lube is needed. Lee Collet Neck Sizing Dies use a collet creating a precisely aligned case neck while reducing run out, and size just the neck and require no lubrication.
This die preserves the perfect fit of your fire-formed cases by sizing just the neck of your cases, thus ensuring greater consistency, accuracy and increased case life, with neck-sized cases lasting up to ten times longer than full length sized cases. Neck sizing should only be used with cases that will be fired in the same gun and is not recommended for autoloaders, slide or lever action guns.
The die has a decapping pin to remove old primers. This Lee Precision reloading die is engineered for shooters who demand accuracy and brass longevity when preparing ammunition for their bolt-action rifles.
