The Sinclair International Shoulder Bump Gage Insert Number 23 is a precision reloading tool designed for handloaders working with 223 Remington, 22 Remington, and 17 Remington cartridges. This insert features a 23-degree shoulder angle measurement capability, enabling shooters to accurately monitor case shoulder positioning during the reloading process. The shoulder bump gage is an essential component for maintaining consistent cartridge dimensions and ensuring reliable chambering in your firearm. Sinclair International’s precision engineering makes this insert a trusted choice for reloaders who demand accuracy and consistency in their ammunition production.
However, I recommend verifying the specific technical specifications and features directly through Sinclair International’s official documentation or contacting your supplier to ensure the description aligns with the manufacturer’s verified specifications before publishing.
