The Best Suppressors For .300 Win Mag
When you think about some of the legendary big-game calibers out there, the .300 Win Mag comes to mind for many of us. Introduced in 1963, the "300 mag" has a pretty strong following among hunters and shooters. It is also a cartridge that lends itself well to being outfitted with a suppressor.
The .300 Winchester Magnum cartridge may be over 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.
Why would you shoot a .300 WM?
The obvious reason to shoot a .33WM is for big game hunting. Elk, moose, deer and bear hunters have been using them for decades and a lot of game animals have fallen to the cartridge. The cartridge lends itself to some versatility, too. Run heavy bullets and you get a ton of down-range energy. Loaded with a smaller bullet and you have something that will truly reach out and touch something, and still have some muscle behind it. I know a lot of spring black bear hunters who swear by the .300 WM.
The .300WM is a popular choice for long-range shooting, although now that the PRC cartridges are out and rapidly growing in popularity, there are a few less shooters running the .300WM. It still has a place with select sniper units for law enforcement and military applications, too.
For a personal standpoint, I've always been a fan of the .300WM. As you may have guessed from some of the other posts I've written, I like big guns. My go-to rifle is a 7mm Rem Mag, which was developed as Remington's answer to the .300WM. I also like shooting any .375 H&H. I like guns with a lot of oomph behind them, although I draw the line at shooting things like a .470 Nitro Express double rifle. It was cool to shoot, but it kicked so hard, my kids came out with loose fillings.

Variations on a theme - .300WSM and .300PRC
While the .300 WM is very popular, there are a couple of variations on the theme that have a strong following. Mainly I'm talking about the .300 WSM, or Winchester Short Magnum. There is also the newer and increasingly popular .300 PRC. If you want to know what is the best suppressor for the .300WSM, or the best suppressor for the .300PRC, the selections that follow are the same as they are for the .300WM. They are all great for all magnum .30-caliber cartridges.
The best suppressors for the .300 magnums
Here are my picks for the best suppressors for any .300 magnum variety rifle. I picked them based off my personal experience, feedback from our engineering team, and most importantly, from feedback from our customers.
Editor's Choice - BANISH 30 Gold-V2

An exceptionally versatile suppressor, the Banish 30 Gold-V2 is rated for calibers from rimfire up to .300 RUM, making it a great choice for a shooter using .300 Winchester Magnum cartridges. Where the Gold-V2 stands out is the larger blast chamber. With this expanded chamber, the suppressor does a better job handling the muzzle energy from magnum cartridges.
All Banish suppressors have been designed for unmatched sound suppression, and testing shows that the 30 Gold-V2 reduces the report by 36 decibels. The average sound level heard by shooters from the Banish 30 Gold-V2 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-V2 is an 8.2-inch quick detach suppressor holding 11 baffles. It uses an industry-standard hub mount giving you versatility when using your silencer. 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-V2 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 .300WM, .300 WSM, and .300PRC.
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
Specs:
- Weight: 13 oz
- Length: 8.2"
- Finish: Cerakote
- Materials: Titanium
Price: $1,399
Editor's Runner Up Pick: 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
Dead Air Sandman-S Specs
- Weight: 17.7 oz
- Length: 6.8"
- Finish: Cerakote
- Materials: Stainless Steel and Stellite
Price: $999
Best Hunting: Banish Backcountry

When it comes to hunting suppressors most of us tend to look at two important things - sound suppression and weight. The BANISH Backcountry suppressor was designed for serious hunting and boy does it ever succeed at it.
The Backcountry is a .30-caliber, fixed-length suppressor that measures 5.5” in length (5.7 with mount) and weighs just 7.8 ounces. That’s a full 1.3” shorter and 2.2 ounces lighter than the BANISH 30 in its short configuration. That may not sound like much, but it makes a world of difference for backcountry adventurers who carefully pack their gear with size and weight in mind.
Rated for calibers up to the .300 Remington Ultra Magnum (RUM), the BANISH Backcountry utilizes six baffles that drop the decibel level down to 137 dB for .300 Win Mag, and 138 dB for .300 RUM at the ear – both of which fall below the hearing-safe threshold. Click here to learn more about how a suppressor protects your hearing.
Utilizing a 1.375×24 Universal Mount, the BANISH Backcountry is a direct-thread suppressor designed to eliminate any extra weight associated with a muzzle device method of attachment, but it is also available with an optional muzzle brake attachment.
When size, weight, and sound suppression are of the utmost concern, the BANISH Backcountry suppressor allows you to pack in ounces, shoot at hearing-safe levels, and pack out pounds
Why We Like It:
- Compact yet powerful
- User-serviceable for easy cleaning
- Titanium offers great strength with minimal weight
Banish Backcountry Specs
- Weight: 7.8oz
- Length: 5.5 in.
- Finish: Cerekote (black or FDE)
- Materials: Titanium
Price: $1,099
Popular Pick: SilencerCo Scythe-TI

The Scythe-TI is SilencerCo's first all-titanium suppressor. It is very popular because it is from SilencerCo, and for being small, light, and for helping reduce recoil. The recoil reduction comes from a single anchor-brake port that helps divert gasses from the shot and reducing the felt recoil on your shoulder.
The Scythe-TI is a direct thread suppressor that comes with a 5/8 x 24 titanium direct-thread mount. It can handle all the big .300 magnum cartridges just fine, too.
Why We Like It:
- Compact and lightweight
- Anchor brake to reduce recoil
- SilencerCo quality
SilencerCo Scythe-TI Specs
- Weight: 7.3 oz
- Length: 6.16 in.
- Finish: Anodized Titanium
- Materials: Type 5 and type 9 titanium
Price: $1,174
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. And the added benefit is that there is a wealth of ammo available. While it may be a bit harder to find some of the other popular variations on the shelf, like .300 Weatherby, .300WSM, .300 PRC, and .300RUM, most decent sporting goods stores will have a few boxes of .300WM sitting there waiting for you to buy them.
Plus, variety is the spice of life, so why not shake things up a bit? I have yet to meet a cartridge I truly don't like - Although like I said earlier, I'm not rushing out to shoot a .470 NE again anytime soon.
