airarmsandy Posted March 8, 2016 Report Share Posted March 8, 2016 hi all, ive got a 40ft/lb daystate huntsman and I'm looking for the best silencer, or should I be having it taken back to 30ft/lb to try and make it quieter? thanks Quote Link to comment Share on other sites More sharing options...
oldypigeonpopper Posted March 8, 2016 Report Share Posted March 8, 2016 hello, 40 seems very high and must use a lot of air and not many shots per fill, at 12ft llb these are good to 40mtrs in .177 if it were me i would try 26 ft llb or about that for FAC then good to 60mtrs plus. what silencer do you have on the rifle? reduce the power and see how that goes ?

airarmsandy Posted March 8, 2016 Author Report Share Posted March 8, 2016 I currently have one off a 22rf on it, that's why I was wondering on peoples opinions on the best to buy? Quote Link to comment Share on other sites More sharing options...

figgy Posted March 8, 2016 Report Share Posted March 8, 2016 (edited) Id be putting it over a chrono and seeing how far down I could go and still be able to shoot flat. Friend of mine used to wind his fac air up to max until he realised there was little to gain speed wise but more negatives. He stays around 30 to 35 ft lb now unless using some heavy lead. Think a good shroud may work better for you than a silencer. Edited March 8, 2016 by figgy Quote Link to comment Share on other sites More sharing options...
evo Posted March 9, 2016 Report Share Posted March 9, 2016 simple answer to your question is ,, lower the power to 30ftlb, running at 40ftlb will do nothing in a huntsman other than empty the cylinder and also cause instability in the pellet, lower it to 30ftlb then fit a twink or weihrauch silencer and the world is your oyster, huntsman classics were not built to run over 30ftlb so why your rifle is running at 40ftlb is beyond me,,the only 3 rifles that were built to run over 40ftlb were the airwolf , the air ranger and the 303 wolverine, others have been turned up and modified but doing that gains no advantage, stick to 28/30ftlb and your huntsman will shoot better and will also be a lot more accurate Quote Link to comment Share on other sites More sharing options...

Dekers Posted March 9, 2016 Report Share Posted March 9, 2016 (edited) Do you want/need 40ft lb or 30ft lb? I never follow these threads. You set up or buy a gun for what you want to do with it, so, if you want 40ft lb, work with it, if 30 will do why are you running it at 40, will even lower work? Rimfire moderators are seldom great on FAC air, there are Air moderators that will work better, and some of those will contain acoustic wadding. Acoustic wadding is seldom used in rimfire mods due to heat and pressures. Edited March 9, 2016 by Dekers Quote Link to comment Share on other sites More sharing options...

evo Posted March 9, 2016 Report Share Posted March 9, 2016 totally agree with the above two posts Don't forget that you are running a pellet past the speed out sound, and the small sonic boom as the pellet leaves the barrel isn't possible to silence.If you brought it under 22ft/lbs (if it's a .22 firing a 8 grain pellet) you'll see a big difference. minimum I would use on a .22 FAC air rifle would be a 15.89g jsb, 8 grain would be for .177, Quote Link to comment Share on other sites More sharing options...
airarmsandy Posted March 9, 2016 Author Report Share Posted March 9, 2016 the huntsman is running at 40 becuase thats how it left the factory, on daystates website they tell you the shot count at 40 and at 30 and its nearly double. il have iot tuned back to 28 or 30 and fit a better mod. thanks for all the advice Quote Link to comment Share on other sites More sharing options...
Salop Matt Posted March 9, 2016 Report Share Posted March 9, 2016 Been preaching it for years. Anything over 30ft lbs is a waste and harder to silence I agree with the above, Mine runs at 30ftlb. From experience for silencers I would recomend: Huggett shroud and standard length silencer but this is expensive but the best. A&M Twink MK2 - Alot cheaper and to reduce length I would get your original Daystate shroud chopped down. Twink cost is £40 and then it would be the cost of your shroud chop. Both these options are far better than any SAK, Whisper, HW, Daystate, IBN etc offerings. Testing behind this was done indoor and unanamously agreed by 5 people.

If you brought it under 22ft/lbs (if it's a .22 firing a 8 grain pellet) you'll see a big difference. Are there any 8g .22pellets? (probably somewhere I suspect), but why you would be using them in a 40ft lb FAC? Anyway 16g pellets will give you around 1060ft sec at 40ft lb, (approx. speed of sound, = 1116ft sec) so below, if you are using magnums you will be way below the speed of sound, so hopefully the boom will not be an issue.

Dasher Posted March 9, 2016 Report Share Posted March 9, 2016 Forget about power and concentrate on pellet speed. Almost any pellet traveling faster than 950ft/s will start to lose stability and thus accuracy, 40ft/lb would need something like a 30gn+ pellet in order to achieve a stable speed, 16gn pellets such as JSB exacts travel at about 900ft/s with 30ft/lb and will give the same trajectory as 40ft/lb with 30gn but will use far less air, what do you really get from a 30gn pellet than 16gn........ not enough in my opinion. 30ft/lb moderates very well with a standard HW silencer, RF moderators generally moderate air poorly.

Yeah, I ****ed up. The calculator I used suggested a 8 grain pellet so I just went with it without checking my facts. It's interesting to see the large difference in ft/lbs and fps between 8grain .177 and 16 grain .22 though. Quote Link to comment Share on other sites More sharing options...

psycho Posted March 10, 2016 Report Share Posted March 10, 2016 (edited) Don't forget any silencer you put on a FAC air rifle is classed as a moderator and will need to be on ticket otherwise you wold be breaking the law and would loose your fac I have an mvt variable power air wolf I set it at 920 fps which means it fires a 16 grain at 30lb and a magnum at 40lb with the same trajectory I use a day state reflex which I found to be the best moderator for the day state at FAC levels and its on ticket like the rifle it only adds a few inches as it sits right down the barral I even tried lr moderators and nothing was as good as the daystate Edited March 10, 2016 by psycho Quote Link to comment Share on other sites More sharing options...
oowee Posted March 10, 2016 Report Share Posted March 10, 2016 I have a 40lb air ranger according to chairgun its doing 1065fps its quiet with the factory fitted mod shoots as flat as my rf and is more accurate than me. Quote Link to comment Share on other sites More sharing options...

The propellant ignition crack and heat on LR is totally different to a high pressure air blast from FAC air (even though air under pressure will inevitably warm up to some extent), and very commonly the energy (although not always) is much higher in LR than FAC Air. They may both be called moderators and look similar externally, but the internals will generally be of significantly different construction, hence why Air Mods are not usually great on LR (sometimes totally inappropriate/dangerous) and LR are not usually great on Air.

markg Posted March 12, 2016 Report Share Posted March 12, 2016 I have 40ftlb air ranger with shrouded barrel,and daystate carbon mod. It sounds really quiet to me. Rabbits done run off when ones been shot. using 21g bisley magnum Quote Link to comment Share on other sites More sharing options...
airarmsandy Posted March 12, 2016 Author Report Share Posted March 12, 2016 oh yes its on my ticket for the moderator, was just interested what was out there as the best one for the job, im going to put it back down to 30ft/lb when the dealer sends it away for me, then try either a daystate or twink mod. thanks all who replied to this thread its been a great help Quote Link to comment Share on other sites More sharing options...
