has been producing high quality precision reloading tools for over 80 years. The Max Cartridge
gage gives reloaders the ability to check all critical maximum SAAMI
cartridge dimensions of straight wall cartridges - mouth diameter, base diameter, rim thickness and diameter, case and overall length and bullet diameter.
If your cartridge will fit into the gage, it should fit in any firearm chambered to SAAMI specifications for this specific cartridge.
Not all firearm chambers or magazines are designed to SAAMI specifications.
