The Sinclair International #35 35" Shoulder Bump Gage Insert (up to .338 caliber) is a precision reloading tool designed for handloaders who prioritize accuracy and consistency in custom ammunition development. This insert is essential for measuring the shoulder datum line of bottleneck cartridges, allowing shooters and reloaders to optimize their loads effectively.
Bump gages function by establishing a reference measurement from the cartridge shoulder to the case head, which helps reloaders determine precise neck-to-shoulder clearance and maximize brass life. The #35 insert is compatible with popular magnum calibers such as .300 Win Mag and .338 Lapua Magnum, making it a versatile tool for various applications.
This gage insert is ideal for serious handloaders, precision rifle competitors, and gunsmithing professionals who require repeatable and reliable load development. Its compact design and lightweight construction ensure it integrates seamlessly into any reloading setup without adding unnecessary bulk.
