By indexing directly from the projectile ogive to the cartridge base rather than measuring across variable projectile tips, it eliminates discrepancies caused by tip variations that can range up to 0.025 inches.\u003c\/p\u003e\n\u003cp style=\"margin: 1em 0;\"\u003eCrafted from durable steel, this tool easily attaches to standard caliper blades and accepts interchangeable inserts to measure a wide range of bore sizes.
