The Best Suppressors For .300 Win Mag 2024

The .300 Winchester Magnum cartridge may be almost 60 years old, but it’s still a serious cartridge that is capable of holding its own even as the 21st century has brought about myriad competitors.

Based on the .375 H&H Magnum and .338 Winchester Magnum cartridges, the .300 Win Mag is a high-performing belted, bottleneck magnum cartridge. Of course, the power that comes with this caliber also creates a lot of noise. Thankfully, there are a wide variety of suppressors available today that are capable of bringing down the decibel levels of the .300 Win Mag. As an added bonus, the use of a suppressor will also help tame some of the felt recoil.

So, without further ado, let’s take a look at some of the best suppressor options for the .300 Winchester Magnum.

Suppressor #1: Dead Air Sandman-S

Dead Air’s Sandman suppressors have great reputations and with good reason. The Sandman-S is the “little brother” to the Sandman-L, and while it may be smaller, it still retains all of the performance. Featuring a low blowback design, the Sandman-S is touted for not only its compact construction but also for its impressive noise reduction at the ear. It does a great job at taming the decibels you hear when you touch off a round of .300 Win Mag.

The Dead Air Sandman-S features a quick-detach mounting system that incorporates an index pattern for ease of mounting and removal. It’s also outfitted with a removable front-end cap, making the Sandman-S extremely user-serviceable, allowing for quick disassembly, cleaning, and fast reassembly.

Why We Like It:

  • QD mounting system for easy on-off
  • User-serviceable for easy cleaning
  • Great sound reduction for the size

  • MSRP: $1,049

Suppressor #2: Banish 30

The Banish 30 is a direct-thread suppressor that mounts on conventional 5/8×24 threads and comes out of the box as a 9″ suppressor holding eight baffles.

If, however, you’ll be shooting suppressed in tighter, more confined spaces, or you just don’t want as much can hanging off the end of your barrel, then you’ll benefit greatly from this suppressor’s modularity. It can easily break down and assemble into a 7″ configuration with six baffles. Either way, you’ll still get great sound suppression with minimal added length on your .300 Win Mag rifle in either configuration.

Weight is just as important as the overall length in this situation. The Banish 30 is made from a strong titanium alloy for unmatched durability at an extremely lightweight. In the full configuration, it weighs 13 ounces; in the short configuration, it weighs just 10 ounces. You’ll be hard-pressed to even feel it on the average rifle chambered in .300 Win Mag!

When it comes time for cleaning, the Banish 30 easily comes apart from both ends and is ready to be tossed in a tumbler, ultrasonic cleaner, or cleaned manually. Reassembly is a breeze due to the baffles being keyed and indexed for exact alignment.

Why We Like It:

  • Modular design to fit specific needs
  • User-serviceable for easy cleaning
  • Titanium offers great strength with minimal weight

Banish 30 Specs

  • Weight: 10 oz or 13 oz
  • Length: 7″ or 9″
  • Finish: GunKote and DLC
  • Materials: Titanium
  • MSRP: $979

Suppressor #3: SilencerCo Omega 300

SilencerCo’s Omega 300 is the lightest, shortest, quietest, full-auto-rated, titanium silencer in its category. If you like to have choices and options, it even comes complete with direct thread and fast-attach mounts, as well as a removable Anchor Brake to reduce recoil, which can be replaced with a flat front cap if you don’t need the brake.

The Omega 300 is popular for all sorts of .30-caliber chamberings, including the .300 Win Mag cartridge. That makes it one of the best multi-caliber suppressors in its class, so it will be right at home on a variety of other rifles, too. You aren’t just limited to the .300 Win Mag, so try it out with .308, .30-06, .300 Blackout, etc.

Why We Like It:

  • Multiple mounting options come with it
  • Comes with a brake in the box
  • Best in class specs in its category

SilencerCo Omega 300 Specs

  • Weight: 14.8 oz
  • Length: 7″
  • Finish: Black or FDE
  • Materials: Cobalt, Inconel, Stainless Steel, and Titanium
  • MSRP: $915

Suppressor #4: Banish 30 Gold

An exceptionally versatile suppressor, the Banish 30 Gold is rated for calibers from rimfire up to 300 RUM, making it a great choice for a shooter using .300 Winchester Magnum cartridges. All Banish suppressors have been designed for unmatched sound suppression, and testing shows that the Banish 30 Gold reduces the report by 36 decibels. The average sound level heard by shooters from the Banish 30 Gold is 132.9 decibels!

Like all Banish suppressors, the Banish 30 Gold is made from a strong titanium alloy that results in unmatched durability at an extremely lightweight of just 13 ounces.

The Banish 30 Gold is an 8.2-inch quick detach suppressor holding 11 baffles, and comes with two 100% titanium muzzle brakes (1/2×28 and 5/8×24). Completely user-serviceable, you can disassemble the suppressor for cleaning in a tumbler, ultrasonic cleaner, or by hand. When you’re ready to put it back together, the baffles are keyed and indexed for hassle-free reassembly.

Perfect for everything from a fun time at the range to big game hunting, the Banish 30 Gold will significantly reduce the report and recoil of large-caliber rifles (up to 45% in testing), while still being effective on rifles down to rimfire calibers. That recoil management is important when it comes to the .300 Winchester Magnum.

Why We Like It:

  • User-serviceable for easy cleaning
  • Comes with multiple mounts, a pouch, a cover, and a baffle removal tool
  • Titanium offers great strength with minimal weight

Considering .300 Win Mag Ammo?

You might already have a gun chambered in .30-06, .308, or some other .30 caliber cartridge, and that might have you wondering why you’d consider adding .300 Win Mag to your lineup. Despite being surpassed by newer cartridges since its introduction in 1963, the .300 Win Mag is still the most popular .30 caliber magnum cartridge among shooters in the United States.

Perhaps you’re looking to do some big game hunting for bighorn sheep, elk, or moose. Or maybe you’re into long-range competition out to 1,000 yards. Even though those are totally different applications, the .300 Win Mag is right at home in both scenarios.

With bullet options ranging from the flatter-shooting 165-grain to the harder-hitting 200-grain selections, there’s a .300 Win Mag load for every need.

Plus, variety is the spice of life, so why not shake things up a bit?
