There'll be an explanation for the 338 being louder than the magnus in a few days.

I'd think it would be the large bore diameter of the 338 but idk... Would also explain the lower SE numbers with the 338. Any chance of the same test on a 223 bolt action happening?

A couple guys have argued with me "556 AR-15 will never be quiet, no matter what“.

I usually just send them that old video of the dominus with the 058 port.

This is quite impressive indeed.

Will you ever run the same test on longer ar? Like 12.5 and 16? Just curious if the 338 does better with more complete powder burn?

I will run them on longer barrels. Zak has some 12.5"s I see rifle Speed has some complete ones. I'll run a test on that

135db piped straight into your ear holes isn't quiet. It may be better than 145db but neither are going to feel very good without hearing protection. Less bad? Sure. Quiet? Never.

    135 is less gas in your face than 145

    How much compared to 172 dB?

    I'm a big fan of going from "holy shit my head feels like it just took a few punches" to "I can loosely wear a set of crappy foam earplugs" when shooting SBRs.
