A quick video on a few things I have noticed about moderators not all being the same. Some accuracy changes.

MODERATORS VS ACCURACY VIDEO: Does it change accuracy?

They certainly can have an impact. Anything on the end of your barrel can have some impact. Things that come into play are 1) it's a weight on the end of your barrel so it changes the natural frequency of the barrel, and mildly affects the dynamics of the entire gun 2) the air currents in the moderator can have some small impact on your pellet / slug trajectory.
If you have a moderator with some built-in air stripper that cleanly relaxes the pressure behind the pellet/slug, point 2 shouldn't be much of an issue, but even then, assymetries in the moderator itself could have some impact. And I imagine in a pellet gun, item 1 probably won't be much of an issue. To deal with 2, the kind of thing that is effective is a moderator that is integrated into a big barrel shroud.
I bet if you put your moderator internals, i.e. the baffle shapes, against your groups, you'd notice a pattern.

I believe the precision/accuracy as a definition comes from the barrel. And there are components of a single barrel that each play its own role, so lets take it all of them in most perfect function.
Anything you attach to a barrel - in a best case scenario - will keep that precision/accuracy, but in average will just make it worse.
Ones the projectile leaves the rifling/muzzle (contact) there is no science that can "fix" things.
Any sort of air stripper only strips off the air blast that kicks the pellet or a slug skirt/edge (but only up to a certain decree), otherwise the projectile will just more-less tumble.

every silencer i used sounds different on any one gun love the hw silencer very quiet on the hw line of guns and the wylie is my most favorite and accurate iv used size also matters i think iv tested larger isnt always more quiet great test jaydog that fx donny is a great silencer also

In my experience, both in Poweder Burners and Airguns, a well designed and fitted silencer will cause a difference in Point of Impact, but not a difference in ongoing accuracy or precision. Since Accuracy can be defined as hitting the thing at which you are aiming, a silencer/moderator can cause a one time change in accuracy, but once this is adjusted for there should be no accuracy problems.
With respect to consistency and precision, i have seen either no effect, or occasionally a small improvement. In my opinion any improvement is likely due to the shooter being more “relaxed” behind a quieter gun. Obviously this is more pronounced in powder burners than in most airguns.

It’s been my experience like as mentioned above, that different moderators have different effects on accuracy and precision. Some make it worse. And in some rare cases, they can improve accuracy. My .22 DS RW HP with ZerodB Moderator is MORE accurate with it than without. Some on AGN will tell you that’s impossible, but it’s my observation with thousands maybe tens of thousands of pellets shot through the gun in practice, hunting and competition. Also, my .25 Delta Wolf is just as accurate with the STO Falx moderator as without it. IMHO only.

When I owned a Hatsan BT65, .25 it DEFINITELY was more accurate with the Donny Ronin on it. When using it on my Royale 500 or Boss accuracy doesn't change but I have to re-zero due to "droop" from its weight. On my Bobcat nothing changes except decibels.

I notice a moderator that has closer tolerance to the pellets size throws off the pellets more than having the hole size larger to the pellets size, bringing back the accuracy to a bare barrel

I don't doubt any of the above posts, but my experience might be a bit different. Obviously, anything you hang on the barrel is, in effect, a tuner, and will affect harmonics, thus maybe accuracy. In my experience, adding a moderator consistently lowers POI, no surprise. In terms of accuracy, I have never seen an effect, with one exception where there was slight occasional clipping. My guess, the instances noted of improved or diminished accuracy with the moderator have much less to do with air flow management, and more with the simple harmonic effect of the weight. Other than the obvious exception of clipping, I think there is one more, and I'll just call it "almost clipping". I think it is possible for the pellet to pass so close to an internal baffle, but without contact, that the pellet can be slightly upset. I could be wrong.

No your correct, yes exactly that, John Neilson Clague who makes moderators, northen Califonia believes keeping the hole size close to the size of the pellet but that's tricky with possibly clipping and of course POI issue but also he's thinking, keeping down the report.... true in most cases.
The closet I've seen right out of the box accuracy is Silent Thunder Ordnance Accipiter he's highest researched most expensive moderator, love it

carbon shroud all the way back threaded like oem plus different barrel alignment spacer plus lr stiff barrel and wylie silencer deadly accurate

I only have experience with printed plastic mods from Airgun Universe. They work very well at noise reduction on my springers and my AA S500. I noted no difference in accuracy, but definitely different poi.

Hopefully I’m not hijacking this thread. Why do you use moderators. I agree they reduce sound a bit but I already don’t need hearing protection with air guns. Is it beneficial to hunting as far as subsequent opportunities because you’ve terrorized the squirrels less? My guns came with moderators so I leave them on but sometimes take them off to hear difference. Bought a sound meter this spring so I’ll be experimenting with and without moderators.

If I didn’t have a mod on my C362, HW95 or my AA S500, I would end up with helicopters flying overhead.
They take thee snap out of the muzzle report. Most of my shooting at home is indoors. With no mod, the cats scatter. With a mod, they look at me and go back to sleep.
Not needed for those that live in more wide open spaces, but here it is a must to remain undetected.

I think it depends…on your tolerance for loud noises, on your gun (firing an Edgun Leshiy 2 without a moderator is quite unpleasant tome), on your location, etc. The only gun I have that i consider quiet enough to shoot at home without a moderator is my Huben K1 .22 My Impacts, Crowns, Wildcat BT, L2, Steyr Pro X, Dreamline, are all too loud for me to feel comfortable shooting extensively without a mod.

Wow really? must live in the woods, may want to think about it why moderators are so popular

Many airguns you don't need hearing protection when using, but some do.
In Canada we can't have moderators on any guns. So speaking as someone that would like to shoot without wearing ear muffs that make my head sweaty, I can attest to the utility of a moderator.

My gun is a Taipan Compact Vet in .25, shooting 25 grain JSBs at 860. It personally hurts my ears to shoot it w/o a moderator.

We have no moderators in Canada, and no drama around it. I am shooting at my gun club, sometimes 5-10 big bore precision rifles beside me. A digital muff alone is not enough to cut the sound and some people using a dual plug protection. But the blast in the lungs is priceless.
What I learned shooting there is more then just the "eyes and ears" command, but the safety + rules + routine handling the gun and amo and people around me + a discipline and sharp thinking and aware of a situation around me all the time +++++.
I can understand not every city has gunclubs or not everybody can afford the membership (yes, you spent all the money on PCPC's and amo), but I am very reserved with the idea plinking around (or inside) a house and using moderators only to hide away from a police raid ... the second - you know or heard about Murphy's Law we don't want to talk about it.
