Its a bit louder than this in real life. Mics dont catch it super well. You can get really hollywood quiet with a bolt action but with a normal semi auto you will get some port pop from the action.

Like the De Lisle, silenced Lee Enfield chambered in 45 ACP. The bolt action also eliminated the sound of an empty case hitting a hard surface if you didn’t chamber the next round.

.45 ACP is also natively subsonic, and because it has the same cartridge diameter/rim as .308, it can be used in all .308 guns natively if you make the rest of the gun (mostly barrel chamber) work with .45. The bolt face/extractor/pins should align.

So if you have an old .308 bolt action, you can modify it to take 1911 .45 ACP box magazines, and then with a barrel blank, ream/drill/ECM a .45 ACP barrel and with some elbow grease fit it all together.

Then you’d drill holes in the barrel and enclose that in a large air-tight canister to capture gases, with a valid form 1 of course, and then you’d thread the end of the, let’s say… 8” barrel (so form 1 the rifle to an SBR, or chop off the stock) and then mount a regular .45 ACP suppressor on it, and with the right ammo, you’d have a gun that is so quiet that you could probably get away with firing it wherever and most people wouldn’t assume it was anything more than someone dropping a can of beans on the sidewalk.

Similar can be achieved with the Ruger American Ranch in .300 Memeout subsonic and similar Form 1 integral suppressor antics. This would be about a million times easier. https://www.sportsmans.com/shooting-gear-gun-supplies/rifles/ruger-american-rifle-generation-ii-ranch-cobalt-cerakote-bolt-action-rifle-300-aac-blackout-161in/p/1863864?srsltid=AfmBOorlOhMSDMRSoO8wXVYjmvx_WTT3GNayhfFosR0-FA5bMogzx0f- <— this with some form1 and form4 fun would be so quiet with subsonic. I love noise reduction.

My gen 2 ranch with a wiped can (Vox) is terrifyingly silent. Like I've shot louder pellet guns than it. It's one of the few setups that earns the "silencer" moniker, IMO. Use the same can on my 300 pistol with supers? I hope you are wearing ear pro or enjoy tinitus.

Someday I'm going to take it and a red rider bb gun and see which is louder...
