What Actually Works on Canadian Game: Your 2025 Cartridge Playbook
The .30-06 Springfield kills moose dead. I've seen it happen cleanly at 200 yards with a 180-grain Nosler Partition, and I've seen it work at 400 yards when the shooter knew their rifle. That round has taken more North American big game than most of us will ever hunt in a lifetime, and in 2025, it remains the standard for a reason—not because it's fashionable, but because it works consistently on animals that weigh 400 to 1,200 pounds.
If you're serious about moose hunting in Canada, you need to pick between three cartridges that actually perform: the .30-06, the .308 Winchester, and the .300 Winchester Magnum. The .308 is the old military workhorse—accurate, available everywhere, and economical compared to magnum rounds. You'll find .308 ammunition at Cabela's Canada and Wolverine Supplies for roughly $1.40 to $1.85 per round for quality hunting loads. The .30-06 sits at about $1.50 to $2.00 per round, same retailers. The .300 Win Mag pushes closer to $2.00 to $2.40 per round because of the extra powder charge and heavier projectiles. All three will handle a moose if you place the bullet in the lungs or on the shoulder.
I prefer the .308 for moose because recoil is manageable—especially important if you're hunting from a tree stand or off sticks—and the trajectory is flat enough at typical hunting ranges. The .300 Win Mag gives you velocity and energy that keeps the energy advantage out past 400 yards, which matters if you hunt open tundra or clear-cuts where moose travel. Pick the cartridge that fits your rifle and shoot it enough to know exactly where it hits. That matters more than the brand name on the box.
Deer Cartridges: Three That Get the Job Done
Whitetail and mule deer don't need magnum cartridges. The .243 Winchester, the 6.5 Creedmoor, and the .30-30 Winchester are the three you should seriously consider, depending on whether you're hunting dense bush or open country.
The .243 is the entry round. It shoots flat, recoil is mild enough for younger or smaller hunters, and ammunition is plentiful. Canadian retailers like Sail and Cabela's stock .243 Winchester loads from Federal, Hornady, and Remington for $1.10 to $1.60 per round. A 100-grain Nosler Partition or Hornady InterLock will drop a whitetail cleanly within 250 yards.
The 6.5 Creedmoor is the modern choice if you want something that shoots as flat as the .243 but carries more energy downrange. Ammunition costs run $1.40 to $2.00 per round at most major retailers. The round was designed for precision rifle competitions, and that accuracy carries into the field. I've used 140-grain Hornady ELD-X loads on mule deer in BC, and the ballistics are excellent out to 400 yards if your rifle is capable.
The .30-30 Winchester is the lever-action standard in thick timber. It's not a long-range cartridge—effective range sits around 150 to 200 yards with iron sights—but it's fast, handling, and reliable in brush where a scope doesn't help anyway. Winchester, Hornady, and Federal all make .30-30 ammunition for $1.20 to $1.70 per round. If you own a Marlin or Winchester lever gun, this is your round.
Bear Cartridges: Don't Bring a Knife to a Bear Fight
Black bear hunting requires enough velocity and energy to penetrate the shoulder. The .338 Federal and the .45-70 Government are the two cartridges I trust on bear.
The .338 Federal is underrated in Canada. It's basically a .308 Winchester case loaded with a .338-inch bullet—plenty of stopping power at reasonable velocities. Ammunition is harder to find than mainstream calibers; expect to pay $2.20 to $2.80 per round when you locate it. Wolverine Supplies and some specialty retailers carry Federal offerings, but inventory fluctuates.
The .45-70 Government is the traditional big-bore choice. It's what was used on grizzly bears in Alaska and Yukon for decades. Modern ammunition with heavy bullets—400 to 500 grains—delivers energy that breaks bone and penetrates deep. Federal Premium .45-70 loads run $2.50 to $3.20 per round. If you hunt in grizzly country, the .45-70 is a legitimate option, especially from a lever gun like a Marlin 1895.
For black bear in the southern provinces, a rifle capable of handling .308 or .30-06 ammunition will work fine, but if you're in grizzly territory or hunting coastal brown bears, the extra mass and penetration of .338 Federal or .45-70 matters.
Waterfowl: Steel Shot Is Mandatory, Period
Canada's waterfowl regulations require non-toxic ammunition, meaning steel shot or bismuth-based loads. Lead shot has been prohibited for waterfowl hunting since 1997. This isn't a debate—use steel or don't go.
Steel shot ammunition for 12-gauge 3-inch magnum shells runs $0.80 to $1.20 per round at retailers like Cabela's and Sail. Velocity typically maxes out around 1,500 feet per second, which is why pellet count matters more with steel than with lead. Most hunters use BB or 2 shot for ducks, switching to larger pellets for geese. Brands like Federal, Remington, and Winchester all make waterfowl loads that comply with regulations.
Wolves and Coyotes: Speed Kills
Predator hunting in Canada requires speed and accuracy. The .223 Remington and the .22-250 Remington are the standards.
The .223 is the practical choice. It's available everywhere—Cabela's, Sail, Wolverine Supplies—at prices between $0.70 and $1.10 per round. Coyotes typically weigh 30 to 40 pounds; a .223 with a 55-grain or 62-grain hollow point is perfectly adequate. Wolves are larger, and if you're hunting wolves specifically, the .22-250 or stepping up to .243 Winchester makes sense for penetration and energy.
The .22-250 pushes a lighter bullet faster—around 3,800 feet per second—making it flatter shooting than the .223. Ammunition costs roughly $0.90 to $1.40 per round. Both cartridges excel at extended range shots where predators are spotted before they're aware of you.
Pick the cartridge that matches your rifle, your hunting terrain, and your skill with that specific weapon. Ammunition availability is better than it's been in three years, and Canadian retailers are stocked. The best cartridge is the one you shoot accurately.
