This video provides an in-depth look at 4-bore stopping rifles, focusing on their historical context, design, and ballistics. Host Ian McCollum, a recognized expert in rare firearms, details the immense power of these rifles, their purpose in stopping dangerous game like elephants, and compares their cartridges to modern calibers. The presentation highlights specific examples from renowned makers like Holland & Holland and discusses the advantages of double-barrel configurations for critical hunting scenarios.

Quick Summary

A 4-bore stopping rifle is an exceptionally large caliber firearm designed for dangerous game hunting, capable of stopping charging animals with immense power. Its caliber is determined by the number of lead balls of that diameter equaling one pound; for a 4-bore, this means a 1/4 lb projectile. These rifles generate around 7,000 ft-lbs of muzzle energy, often featuring double barrels for reliability in critical situations.

Frequently Asked Questions

What is a 4-bore stopping rifle?

A 4-bore stopping rifle is an extremely large caliber firearm, typically a double-barrel rifle, designed for close-range defense against dangerous game like elephants or rhinos. It uses a massive projectile and a large black powder charge to deliver immense stopping power.

How is the '4-bore' caliber determined?

The term 'bore' or 'gauge' is derived from the number of lead balls of that specific diameter that would equal one pound. For a 4-bore, it means a lead ball weighing 1/4 pound (approximately 1,750 grains) is the diameter of the barrel, which is about one inch.

What kind of ballistics does a 4-bore rifle produce?

A typical 4-bore load uses 12-16 drams of black powder, achieving a muzzle velocity around 1,330 fps and generating approximately 7,000 ft-lbs of muzzle energy, with significant recoil managed by the rifle's substantial weight.

Why were double-barrel rifles preferred for stopping dangerous game?

Double-barrel rifles provided a critical safety advantage by offering two independent firing mechanisms. This ensured a hunter had an immediate second shot available if the first round failed to stop a charging animal or if there was a mechanical issue.
