Daystate Moderator length

[Scriv]

I am fairly new to PCP rifles, and moderators. I have a Daystate Wolverine .22 that has a 160 mm Hugget on it, and was thinking about buying a Redwolf HP in .177. My question is there a detriment to having too much moderator on the rifle? Makes sense that when I purchase, I could just borrow the one off my .22 to see how effective it is, but would there be an advantage to dropping down to a 110? Alternatively, is there a disadvantage(beside noise) to not running a moderator at all? Thanks for the help.

Size matters both in moderators and other bits of life.
The bigger the better.

In my limited experience running a 30 cal Huggett Astille with one extension on my 25 cal Avenger Bullpup yields a whoosh of air.
The shorter DonnyFL Tanto in 25 cal has more of a crack but is still quiet enough to use without ear plugs.
Open muzzle is still not loud enough to need plugs but just barely.(or more likely my hearing is worse than I’ll admit!)

The Huggett is about 25% larger (longer) and the Tanto is noticeably louder. Both are close in diameter.
Using two extensions in the Huggett did not muffle the sound noticeably enough to warrant using two in the field but indoors it helps.
The shorter length of the Tanto does not make it easier to maneuver over the Astille.
Logic tells me that shooting with no moderator is more likely to yield higher fps/fpe but I don’t have facts to back that up.

I have not noticed changes in poa/poi using either moderator vs no moderator, sighted in at 50 yds.
Admittedly I need more trigger time with a variety of ammo to hone in on good loads.

A thread on here mentioned running one size over the guns caliber to minimize chances of clipping so I have two different caliber moderators for the same gun.
Check around moderators are as much fun as air guns.

I just shot my new TexanSS 308 for the first time today and using pellets was almost as loud as a 22lr, while a 118gr slug was not only very much more muffled but pleasant to shoot. That was a huge difference that I did not expect.
Now I want to try slugs in the Avenger and hear what happens.
I’ve only owned pcp’s for about six months and have three now, they are addicting

Using a moderator will have no effect at all on FPS or FPE. The moderator is not pressurized, so the additional length has no effect on dwell time in the barrel, therefore you do not have high pressure air acting on the pellet (or slug) for a longer period.

With respect to sound attenuation, my experience is that while bigger is generally better with respect to suppressors/moderators, all other things being equal, a longer suppressor is better that a wider one. In other words, the length matters more than the diameter for any given volume. I generally shoot with moderators on all my guns, with the exception of my Huben K1. The sound from this is sufficiently low that I don't bother trying to further suppress it. On the other hand, my Leshiy 2 is so loud (indoors) without a suppressor that it reminds me of a .22LR.

Thank you both for your well written responses. While reading the first response I began to get the feeling that there were some great shooting projects in there to get answers. As for the second response, I follow, and appreciate your logic. Again, thank you both. This is going to be fun.

Agree with the longer is better. The Evanix .50 is a LOUD Gun! Got a DonnyFL Emporer and that helped.
Added the extension and it's like poof.

As an update for those that may be reading this thread. I did go with the 110 0db. Turns out that it is so quiet that all you hear is the internals of the gun working at the shot. The 160 only made it longer, nothing else changed.
