W.T.F. Silencers’ Silencer Summit Results
Independent, third-party sound data from the Thunder Beast Arms (TBAC) Silencer Summit in Cheyenne, Wyoming.
W.T.F. Silencers put Jackalope, Barron Big Bore, Tatanka, and Marmot cans on real hosts — from 7mm Backcountry and .308 bolt guns to subsonic .300 BLK, pistols, and big-bore platforms — so you can see how our silencers perform where it counts: at the muzzle and at the shooter’s ear.
Jackalope · 7mm Backcountry
280 SS & 280 Ti
Stainless and titanium Jackalope .280 cans tested on an 18″ 7mm Backcountry bolt — real magnum-class host data for a versatile hunting suppressor.
Tatanka Titanium · pistol
106.38 dB·ms
Shooter’s-ear impulse of 106.38 on 9mm pistol — a standout impulse figure from TBAC’s 2026 Summit.
Barron Big Bore
.50 Non-BMG
Coverage across .308 bolt, .375 RUM, .500 S&W subsonic, and .50 Beowulf — one big-bore can, multiple serious platforms.
Marmot · compact 9mm
3.0 – 3.8 oz
Lightweight pistol cans tested on 9mm and .22LR — including the Marmot 7 Baffle configuration for when you want more baffles in a still-compact package.

How to read the numbers
- Peak dBA (muzzle avg / shooter’s ear)
- A-weighted peak sound pressure level in decibels. Lower is quieter. TBAC’s muzzle average blends left and right muzzle mics; shooter’s ear is measured at the shooter’s position.
- SE Impulse (dB·ms)
- How much sound energy hits the shooter’s ear over time — not just the sharp peak. Lower impulse often feels “softer” even when peak numbers look similar.
- Shooter’s ear
- The meter at the shooter’s head — usually what matters most for hearing exposure and how a can feels on that host.
- Host abbreviations
- Hosts are labeled in plain English above (e.g. 16″ AR-15 (5.56), 20″ .308 bolt action, 9mm pistol). Subsonic loads are called out where TBAC tested them.

Results depend on host firearm, ammunition, temperature, and setup; they are not a warranty of hearing protection. Always use appropriate hearing protection when shooting.
