We are convinced that we have a product range that will protect your shooting from
objections through noise, and will allow clay shooting facilities to be used more - possibly
for floodlit shooting - since you will no longer cause local disturbance. The simple reason is
that the noise reduction characteristics are so significant that, in normal topography, the
sound is not audible above background noise even at 150 metres with the single shot
Pedretti, and 300 metres with the Hushpower conversion to semi-autos & pumps. Contrast
this with the normal 12 bore which can be heard in still air at 1.5 Kilometres.
Our Hushpower range of silenced products has been subjected to independent tests carried
out by several Environmental Health Departments. All have been extremely impressed and
to date not one planning application has been refused for noise reasons when using our guns.
The silenced guns shoot, handle and feel like any other shotgun once the shooter has had a
moment to familiarise himself with them. They are ideal for beginners and club shooters
since they have negligible recoil and excellent patterns. Many excellent scores have already
been recorded at domestic disciplines.
Vermin control is an area which this gun has no equal, putting a new perspective on serious
vermin control, as well as pigeon and rabbit shooting.
We strongly recommend you use felt wadded cartridges with Hushpower guns, and to
achieve maximum noise reduction use subsonic shells.

TO OVERCOME
NOISE POLLUTION
HUSHPOWER 12-BORE
1. Remove any sighting system from the muzzle. The barrel may be shortened if
required (No shorter than 24” for section 2)
2. 2. Measure barrel diameter at the muzzle. Machine out inside of the rear
(tapered) bush of the silencer to match the muzzle diameter of the barrel. The bush
needs to be a very tight fit and needs to be drifted or pressed on.
It is very important to ensure the rear bush is true to the bore. We suggest that
machining is carried out with the bush fitted to the silencer body (oil thread first) in
a lathe with a large enough head stock diameter.
3. Apply a small amount of retaining compound (i.e. Loctite 638) to the outside of the
barrel by the muzzle, then drive rear bush firmly onto the barrel, no further than 2” from
muzzle.
4. Screw the body of the silencer to the fitted bush. Tighten firmly by hand.

FULL BORE
SOUND
MODERATOR
UP TO .233
For people who enjoy rough shooting with a shotgun, but would like to avoid the anti-social noise the guns can produce, the answer is close
at hand. The Saddlery & Gunroom are now the owner of the famous ‘Hushpower’ name, and can now supply silenced versions of .410 and
l2bore single barreled shot guns, as well as a ‘universal’ 9” silencer for .410’s (which fits to the barrel of your own gun), and they can even add
a moderator to your own semi auto or pump shotgun.
To cock and open the action, it is the familiar side lever shotgun style which breaks the action and exposes the
non-ejector chamber. A cartridge can then be slipped effortlessly into the chamber, and the action snapped closed and made ready to fire.
There is a cross-bolt safety which, although a little stiff in operation, does a fine job of locking the trigger thereby disabling it until required for
firing. Firing impressions were odd at first, as the trigger was squeezed I could hear the firing pin strike the cartridge, before the gentle lift of the
shotgun and a very muffled report from the front end -followed by a plume of white smoke gently escaping from the muzzle. Not only had the
moderator stifled the crack of the .410, but it had greatly reduced felt recoil and muzzle flip, altogether a great improvement over the standard
gun. That was using .410 Eley two inch cartridges with no.6 shot, next I tried Winchester two & a half inch and three inch magnums to see if
there was any great difference. As expected. with the longer case lengths. each factor stated above - regarding the gun’s noise, recoil, and
movement from aim -all increased proportionally. Although this was still far superior to the same cartridge combinations without a sound mod-
erator fitted. Down range tests at 10 yards show good shot dispersal and density from the full choked barrel - this will equate to an effective
range of approximately 30 to 40 yards maximum. It was interesting to see a tighter pattern with the two inch Eley cartridges than the Winches-
ter two & a half inch cartridges. I was very impressed with the gun. and decided to see if the claims that the .410 was inaudible at 50 yards was
true. Having a colleague fire the shotgun with each length of .410 case, I retired 50 yards down range and took protection behind a clay pigeon
trap set-up for safety. The Hush Power was then fired with each cartridge length and to be truthful it was only audible as a muffled pop -rather
like that of an unsilenced air rifle. This was over dead ground, but when firing against a woodland edge there was a small increase in noise
caused by echoing back from the trees but nonetheless, still very quiet.
Conclusions
I can see why these weapons have become firm favorites with professional vermin controllers, game keepers, and people who value minimal
sound disturbance and privacy. The real proof of the pudding was when my colleague and I returned to the farm house to be questioned by the
owner, who wondered if we'd had a wasted journey, because he had not heard any shots! Suffice to say he was well pleased when we
Showed him the 8 rabbits we had harvested, and right there we had a convert to the Hush Power. If you have an existing .410, and cannot
afford the price of the converted shotgun, the Saddlery & Gunroom also produce a universal fitting sound moderator (price £48.61), which is 9
inches long and locks to the taper of the barrel. Owners of pumps or semis can have them silenced at the Saddlery & Gunroom workshops for
around £235, depending on the make of gun.

Bruce Potts tests the Hushpower 12 Bore Moderated shotgun
Having tested the .410 Hushpower moderated shotgun earlier in the year I was eager to get my hands on its big brother in
the form of their 12 gauge system. Nothing really prepared me for the size of the can that forms the guts of the
Hushpower system. At a full two inches in diameter it really gives it that artillery piece prowess, but uncannily it is light
and pointable as well as swinging nicely on the shoulder. This is primarily due to the aluminum outer casing and
honeycomb of the forward baffles and open expansion chamber that contribute little to the overall weight. As with
the .410 variety, the base gun is the classic, folding barrel 12 gauge Pedretti, which is almost unbustable and forms a good
solid base from which to perform the conversion. If you like you can have your own shotguns converted and the supplier -
The Saddlery and Gun Room also provide a moderator for semiautomatic shotguns. which I wilt test in a later issue. If
that doesn’t tickle your fancy then a 9”, .410 unit can be fitted to the end of the barrel which works well but adds to a
gun’s overall length
Can Can
Not so the Hushpower. the full-length moderator is one continuous tube from breech to muzzle with only the inner baffles
adding any extra length at the end. The guts of the system can be seen once the outer sleeve is removed by unscrewing it
from the permanently attached base block that mates with the chamber. Once unscrewed, the outer body easily slides off
to reveal that the barrel has two sets of five, 0.5” holes drilled in parallel approximately 1.5” apart. along its 24” length.
They are positioned at 12 and 6 o’clock to each other. At the end of the barrel is a collar that ensures it sits central to the
outer sleeve. This makes sure the actual tube aligns with a further eight baffles - much like that on a conventional .22
Rimflre moderator which adds further to its sound muting qualities.
So how does it work? Simple - as the shot charge passes down the barrel the expanding propellant gases are bled off via
the ten primary ports. This allows a quantity of gas to escape into the full length outer sleeve to slow down and cool off.
As the shot column leaves the barrel as it passes through the eight further expansion chambers still within the sleeve that
forms a ten-inch extension to the overall length. Finally the column enters the free air followed by all of the propellant
gases. which by this time have cooled sufficiently by their diverted travel around the labyrinth of expansion chambers to
emerge into the atmosphere. It is this cooling action that reduces the usual, un-silenced, booming crack of a normal 12
gauge to that of a Hushpower whimper.
Hamster Sneeze
Mike, the gunsmith of The Saddlery and Gun Room explained - that to take full advantage of this system in a 12 bore gun
it is advisable to use subsonic ammunition. And kindly supplied a couple of boxes of Gamebore’s #7.5. subs, which run at
a velocity of lO5Ofps so keeping below the sound barrier. It therefore does not have that sonic boom characteristic of
standard velocity ammunition. Couple these with the Hushpower’s efficient silencer system and you have a muzzle report
that sounds like a hamster sneezing. The data that came with the gun stipulates that at 100 metres a standard 12 bore
produces 90.0 dB of noise, which only drops to 80dB at 300rn Whereas the Hushpower firing subsonic ammo produces
half that at 100 meters. (45.°Db) and is inaudible at 300m. Ambient/background noise was set at 44Db so you can see that
even at 50m the Hushpower is nearly inaudible to an onlooker. This has great advantages if you run a clay shooting
ground that has problems with noise pollution. Especially as a standard 12 bores retort can be heard at up to 1.5
kilometers. Mon importantly. it allows me to efficiently conduct pest control in semi urban areas and stabling without
drawing too much attention to myself or belying my position to any wary game. This is especially useful when elevated
snots have to be taken at say a squirrel were a .22LR not possible due to the excessive carry over.
Operation Hushpower
This is the theory, so to prove it, I went to a friend’s paddock and stabling area which had become almost unusable due
to the rabbit excavations. Rimfires rifles are no go. due to outlying buildings and air rifles have taken their toll on
numerous lamping sessions, and running snots where a 12 bore shines could not be attempted.
The basic chassis is a single-shot Pedretti and typical of its breed is a simple gun to use. The Hushpower versions loses
nothing in handling or performance. Push the top lever, which also cocks the trigger, to the right and the action will swing
down to open. it’s a non-ejector so the empties have to be removed by hand, but this isn’t a problem. Like the un-silenced
version the barrel can be fully folded back to meet with the stock to form a very compact Package.

Bruce Potts tests the Hushpower 12 Bore Moderated shotgun (continued)
All you now have to do is drop in a shell and snap the barrel shut and you’re ready to fire. A simple cross-bolt safety
manually secures the trigger and the low comb beech stock with plastic Putt pad ensures proper sighting down the barrel
albeit a tad larger than normal! The trigger itself is a bit stiff but it broke cleanly enough. I only say this because, instead
of the ear splitting crack of a normal shotgun you are more conscious of the trigger noise on the Hushpower due to the
decibel reduction. Reduces it? Yes it does. With the Gamebore subs you are instantly aware of the lack of felt recoil. I
reckon almost 40% at the shoulder. which in turn stops muzzle flip. It’s difficult to accurately describe the
report, its a cross between a pre charged airgun with a hollow tin can resonance to it. All in all very quiet, and you
can actually hear the passage of the shot up the barrel, and in flight. If aiming at flying game the noise is
less, than say into a solid background such as a wood as there’s a certain amount of rebound
shockwave but still a considerable reduction from a standard 12 gauge.
Using normal velocity cartridges through the Hushpower quite obviously increases the level of
noise but compared to an un-moderated 12 bore all the sonic boom is removed leaving a hollow
muted report. This is what is evident to the shooter, but a more accurate test is to listen to the report
down range. After all that is where your game is going to be hearing it from anyway. Safe behind a wall
of straw bales at 50 yds, I got my colleague to fire five rounds. Their signature offered no lasting,
carrying noise only a very hollow ‘phut’ with a characteristic ring from the outer sleeve followed by the air
disturbance caused by the shot in flight. At 100 yards and behind a stable block it was difficult to hear the
report above the ambient noise of cars etc. And only the white plume of smoke, which gracefully exits the
barrel, reveals that firing had taken place. Shot patterns were tested on a 30" circle at 25 yards and showed
tight density equates to a fully choked barrel Point of aim was a bit low, caused, no doubt by the increased diameter of the
moderator. The solution - aim a bit higher.
Covert Control
All well and good on primary testing, now to some actual rabbit shooting. The next day provider some good sport. We
moved the rabbits from thistle patches in the paddock. which were untouchable with an airgun. but now became fair game
for the Hushpower. It took a while for them to cotton on to the new tactic of walking up to them and not sneaking about
on all fours! After 12 hushed shots with little felt recoil - 10 rabbits were accounted for before they all became wise and
stayed put - below ground. Where this seemingly unusual system comes into its own is in situations like the stable area.
here an un-silenced 12 bore would be out of the question but the Hushpower shines. In this world of politically correct
attitudes and our sport being under the microscope, not making a song and dance about your shooting is greatly
appreciated. That’s why so many professional pest controllers and companies use Hushpowers in all their forms, to
dispatch quarry quietly and effectively, you can’t get greater praise than that. If you want to drop into The Saddlery and
Gun Room, either Howard or Jon will be more than happy to show you the Hushpower system.
The single barrel Hushpower. Full choke 45 Db at firing point and usually inaudible at above
ambient background noise at 150 meters. Weight of gun: 7 lbs
Semi auto Hushpower conversion includes Two shot capacity mag job to conform to UK
specification. This will add just over 1 lb. in weight to your gun.
Calibres available in 12 bore and .410
The moderator assembly is a permanent conversion which can be removed for cleaning.
The sound at the firing point for the auto is similar to that of a .22 rimfire rifle, and the gun is usually
inaudable above ambient noise levels at 300 metres.

Tests the Hushpower Mossgerg 500 Pump 12G Shotgun
Ridiculously long but surprisingly effective...Ian Davies tests The Saddlery & Gunroom's Mossberg 500
pump-action shotgun, fitted with their own Hushpower moderator system.
Nowadays, just about any firearm can be fitted with an effective moderation system to reduce noise and firing
signature. In the beginning it was just 22Rimfires, now it seems to be everything from 17 Remington right up
to the big full bore Centrefires. Certainly anything going supersonic will show less reduction, but that's not to
say the end result isn't significantly different, or for that matter effective… And in terms of effectiveness there
are a number of advantages; a reduction in hearing damage to the user, the quarry is spooked less, which in the
case of pest controllers looking for high body counts is useful, and also less environmental disturbance - and
that includes annoying people who live near to where you are shooting, especially at night. All this holds true
for firearms and to a degree airguns too, but one area that has always been considered un-silenceable is shot-
guns. Why, I'm not really sure, but perhaps it's that big, deep boom as they fire that gives this impression. They
may offer a much lower velocity than a fullbore rifle, but that rolling signature can be heard for miles.

“The Model 500 is one of the most practical pumps, available and shows good features like its skeletonised
shell lifter and tang-mounted safety catch”
"The firing signature is the weirdest thing I have ever heard - it makes a dull snick crack as it goes off"
"All this holds true for firearms and to a degree airguns too, but one area that has always been considered un-
silenceable shotguns"
