If you’re in the market for a cartridge belt — whether for yourself or as a gift — one of the most important choices you’ll make is the gauge size. A cartridge belt must match the shotgun shells it’s designed to carry. Get it wrong, and you’ll end up with shells that slip out or don’t fit at all.
So, how do you know which gauge is right for your cartridge belt? Let’s break down the most common shotgun gauges — 12GA, 16GA, and 20GA — and help you choose the perfect fit.
Why Gauge Matters in Cartridge Belts
Gauge refers to the diameter of the shotgun shell, and it directly affects the size of the loops in your cartridge belt.
► Too loose, and shells fall out while walking through brush.
► Too tight, and reloading becomes frustrating when you need speed.
That’s why a properly sized, custom-fit cartridge belt is essential — especially for hunters who spend hours in the field.
12 Gauge: The All-Purpose Powerhouse
The 12GA is the most popular shotgun gauge worldwide, and for good reason. It offers a balance of power and versatility, making it ideal for everything from bird hunting to big game.
► Best for: Duck, goose, turkey, deer, and all-purpose hunting.
► Cartridge belt choice: A 12GA cartridge belt with 25–30 loops provides plenty of capacity for longer hunts.
► Why hunters love it: The 12GA offers more stopping power and ammunition variety than smaller gauges.
👉 If in doubt, and you know the hunter uses a standard shotgun, chances are 12GA is the right choice.
16 Gauge: The Balanced Classic
The 16GA used to be one of the most popular gauges but is less common today. Still, many upland and traditional hunters swear by it, thanks to its balance of power and lighter recoil compared to the 12GA.
► Best for: Upland game like pheasants, grouse, and rabbits.
► Cartridge belt choice: A 16GA belt with 20–25 loops keeps it lightweight and practical.
► Why hunters love it: It offers nearly the punch of a 12GA but with less weight, making it easier to carry in the field.
👉 A great middle ground for hunters who value tradition and balance.
20 Gauge: The Lightweight Specialist
The 20GA is lighter, easier to handle, and a favorite among bird hunters and younger shooters. It offers less recoil, making it comfortable for long days in the field.
► Best for: Quail, dove, woodcock, and smaller game.
► Cartridge belt choice: A 20GA belt with 20–25 loops offers just the right capacity without extra bulk.
► Why hunters love it: Lightweight and comfortable — perfect for hunters who prioritize speed and agility.
👉 If the hunter values mobility and light gear, a 20GA belt is a smart pick.
