Suppressor on a break-barrel?

[pdxFrank]

Hello shooters, I'm back with the results. Sorry that took a minute, other things in life to triage.

Since it's but one example, it'll take more than that to convince me they're good/bad for ALL break-barrels.

I have two HW50's with DonnyFL's on them, Tanto on one and a Sumo on the other.
I don't have a decibel meter, but I can say 100% the suppressors make them much quieter.

Both my 50's are tuned and the mechanical noise is really low though.

I was surprised how loud your gun was with the suppressors mounted ?

i have Benjamin Trail SBD, silent but deadly. It is very effective. Entire rifle was inexpensive.

Frank,

Thanks for testing and sharing your results. Very well made video!



Any idea why the loudness varied so much between shots?

Because the more variation between shots — the more shots you need to measure in order to get an average that you can be certain it is truly representative of the loudness at that configuration — and not just a coincidence of bad-luck-shots (or good-luck-shots).

^^^This. You'll always have mechanical noise in a springer but like Joe said, tuning them will lessen that and lower your numbers at the muzzle along with a heavier weight pellet. Just a guess on my part but try something in the 10-12gr range and see what happens. Random lame thought but is your stock hollow?? If it is, your meter might also be picking up some of the echo from mechanical noise in that synthetic stock unless you stuffed it to deaden that echo. I own a few, hated that echo, so stocks got stuffed to get rid of it.

You might also figure out how to set your decibel meter up downrange so you can shoot over it, run your test again and see the difference there too. Mentioned this because, while no one used a meter testing it, they did the same thing I did and stood in a safe place downrange and had someone else shoot the rifle. Nope, not gonna even remotely claim my hearing is decibel meter exact, but I could hear a difference in the report standing downrange of my rifle.

Look forward to seeing the differences if you give the above a try and make a couple more videos.

Yeah Steve, I'm thinking his meter was picking up some of the mechanical noise.

I've compared my HW80K .22 that has a shorter barrel and suppressor installed to my unsupressed .20 HW80 and the difference is there. Unsuppressed the HW80 is LOUD!

Suppressed the HW80K is very quiet! Even the machinery is quiet.

Yes I think muzzle suppressors actually increase the barrel's balance and ability to "vibrate" more softly for better shots.

Thanks for the great replies all!



That Parrus .177 is about six months old, with less than 1000 shots. I wanted to use something that I could be reasonably sure it didn't have other issues. Same with the KOI, brand new.

So it's noise level is straight-out-of-the-box plus a light cleaning. I figure the wide variance (not as bad WITH suppression it seems) is mostly the gun-noise. Tuned would be better, but it's the only threaded rifle I have.

That's why I shot with the meter just over a foot from the muzzle. Far enough away to avoid air-blasts, but close enough to dominate any other noises.



I will try later how it sounds at further distances. Right now editing a bunch of other guns I tested levels on (non-threaded, so no suppression other than build-in).



Oh, I did 11 shots each and dropped the lowest/highest one of each. I haven't done the math on this video yet to get averages.
