Q&A / FAQ

Fact: A typical centre fire hunting or target rifle produces a peak sound level of between  155 dB to 161dB or more, with every shot fired(  .308win. 155Gr Magtec Factory load produced 161dB in our tests)
Fact: Hearing damage occurs imediately at 150 dB!
Fakt: Bei Aussetzung von Lärmpegel höher als 150 dB wird dauerhaften hörschaden, tinitus oder beides verursachen
Fact: Repeated exposure to sound levels or 150 DB, even when wearing hearing protection will cause hearing damage due to the fact that sound pressure waves are transmitted to the inner ear via cartilage and bone
Fact: Personaly protection equipment such as ear defenders or plugs do not offer satisfactory protection
Fact: You damage your health with each and every shot
Fact: The European Directive 2003/10/EC sets a maximum exposure level at 140DB.
Fact: Bundesministerium der Justiz. ( German H&S legal body) Regulations state

• Paragraph 6. Exposure levels:

1.Higher Exposure Level L (tief) EX,8h = 85 dB(A) beziehungsweise L (tief) pC,peak = 137 dB(C),
2.Lower Exposure Level: L (tief) EX,8h = 80 dB(A) beziehungsweise L (tief) pC,peak = 135 dB(C).
Fact: European Directive 2003/10/EC states that where technicaly possible,  noise pollution should be tackled at source
Fact: Bundesministerium der Justiz. ( German H&S legal body) Regulations state:

• Paragraph 7. protection from noise

(1) The employer is bound by paragraph 3 section1 line 6 to take the nessecary technical steps to ensure noise exposure is minimised and that the order of action is recognised 
1.Noise pollution is to be tacked at source. Technical measures come before organisatory measures or personal protection equipment.

Fact: All users of fireamrs fall under these regulations. It is at Government discression to make exceptions for Military and Law Enforcement Personell.

Fact: The only reliable way to reduce the harmfull noise produced by a firearm is to fit a suitable moderator. It is technicaly possible, it is affordable and the only way to protect your hearing, your hunting dogs hearing and the hearing of any people in your imediate vicinity when you fire a shot.

Sound Moderators where originaly invented by Hiram Maxim ( invertor of the Maxim Machinegun). The reason was to allow people to enjoy shooting in thier back gardens with out disturbing neighbours. Those where the good old days, can you imagine shooting in your back garden today, you'd soon have a police helicopter overhead and a SWAT team at your door, unless you real right out in the sticks that is.
We highly recomend that all users of Fireamrs, be they hobby stalkers or professionals, target shooters or pest controllers should take note of the regulations and ensure that thier hearing is protected by fitting a sound moderator to thier firearms
How many more or us must be deafened before the use of Sound Moderators is accepted Europe wide ?
The illegal use of Sound Moderators is impossible to control, as criminals generaly pay little heed to regualtions
The more important aspect of Sound Moderator use is to reduce the harmfull effects of noice at the source and protect law abiding citizens from hearing damage
The most widely spread health problem within industrial nations is damage to hearing, it costs Germany over 7 Billion Euro's every year, plus countless lost man hours. But what does it cost the individual in quality of life, sleepless nights, restless days. A large factor in many suicides is Tinitus.
Research has shown that individuals regularly exposed to small arms fire in training situations are over TEN TIMES more likely to suffer noise induced hearing loss than individuals not so exposed.  This is despite regular use of protective ear devices, which are supposed to reduce noise levels to below damaging levels.  The cause for this is most likely due to bone and cartilage conduction of the noise directly into the middle and inner ears.  While bone conduction hearing is certainly less sensitive than conduction through the normal ear canal, nonetheless the noise levels produced by repeated gunshots are certainly great enough to cause hearing loss over time.
Please. Protect your hearing, before it is to late.

FAQ
Q:Can I use a .30 caliber Delta Moderator on my .223 Remington?
A: Yes, we measured a 3% loss in reduction ability when fitting one of the larger bore moderators to a smaller bore rifle, but this is undetectable to the human ear and the remaining sound reduction is more than adequate
Q: I am very recoil sensitive and have problems shooting my .375 H&H, I have a trip to Africa booked but my PH has just informed me that I will not be allowed to shoot using a muzzle brake. Can I use one of your moderators on my rifle?
A: yes, we have moderators for use on calibers up to .416 Rigby and the reduction in recoil is around 30%, not as efficient as our muzzle brakes, but a whole lot quieter. You might want to check up on the legal situation with moderators in the country you are visiting though.
Q: I shoot a 7mmWSM, i'm worried about how long alluminium baffles will last on this caliber, are replacement baffles available if i should wear mine out?
A: The 7mmWSM is a fairly intense round, it depends on how much you shoot and how hot you shoot the moderator as to how long alloy baffles will last, We would suggest you replace the first two baffles with TiAIN coates stainless steel baffles, this will certainly ensure you get the longest service possile from your moderator, but only adds around 50g in overall weight. Spare baffles, both alloy and TiAIN coates stainless are available.
Q: I live in Northern Ireland, who should I contact for supply of a Delta Moderator?
A: Well I guess that depends on wether you consider N.Ireland to be part of the UK or not, Give either Sportsman Guncentre or PSE a call, either will help you out.
Q: My rifle is threaded for a Reflex T8 and it has a spigot behind the thread, will your Delta Moderator fit correctly?
A: We have a special expansion chamber rear end that fits spigoted barrel threads, there is a minimal extra charge and they weigh 20g more than the standard thread version.
Q: I live in France, can you supply me with a moderator?
A: Yes, all we require is a copy of your fireamrs licence, we can then supply you directly. We will however soon have an exclusive dealer in France and you can purchase direct from them
Q: I shoot a lot with my 6.5x284, I use it for targets and for foxing, the rifle weighs 12lbs without scope and i'm not bothered about having an ultra light weight moderator, and dont want to worry about burning baffles,  do you have something that will suit me?
A: Yes, we have stainless steel versions of the Delta Moderator
Q: I have a Delta IV. can I add baffles to get even more sound reduction?
A: Yes, spare baffles are available, we tested moderators with up 7 baffles fitted. I wouldn't recomend fitting more than 7 as the moderator becomes fairly long, but adding a baffle or 3 is no problem.
Q: I live in the north of Scotland, can you supply my local RFD with a moderator for me?
A: Have your RFD contact Sportsman Gun Centre, they supply other dealers too
Q: Will my rifle lose accuracy if i fit a moderator?
A: By and large we have seen an improvement in accuracy when moderators are fitted, so no, we doubt very much that a correctly fitted moderator will be detrimental to accuracy
Q: With my rifle zeroed at 100yards without a moderator, will i need to re zero if i fit a moderator?
A: There will always be some shif in point of impact when fittung any muzzle attachment. How much depends largely on the weight of the attahcment and the thickness of your barrel. Test it and see is the only way as all rifles are individual. The shift will however be constant, so you can note both zero possitions with and without the moderator fitted
Q: Will fitting a moderator reduce the velocity of my bullets
A: No, a moderator traps the propellant gasses, but does not reduce velocity of the projectile,
