In principle, any conventional ammunition can be used in conjunction with a silencer. The HAUSKEN silencers in particular offer specific features depending on the application or calibre: the HAUSKEN WHISPER MEGA XTRM, for example, is characterized by the fact that it is also suitable for MAGNUM calibres. If a HAUSKEN silencer is used in conjunction with a short barrel, it is advisable to use the special filling from the RWS SHORT RIFLE series. Among other things, the burning behaviour of the powder has been optimized in these cartridges in order to ensure consistent performance despite the shorter barrel length. The cartridges of the SHORT RIFLE series are currently available in the most important calibres and with the most modern RWS bullets.

Yes, but with a loss of performance in terms of silencing. The silencer achieves the optimal silencing performance when the bullet calibre matches the inner diameter as best as possible. Because the smaller the differences between the bullet and the guidance in the silencer, the less gas can escape the bullet past the silencer. This leeway reduces silencing performance with a smaller caliber. 

You can fire subsonic ammunition with the silencers, but due to the low energy output, we definitely do not recommend these for hunting use. Only a few exceptions in the subsonic ammunition product range achieve the legal minimum energy for hoofed game. Local hunting laws must always be observed here and the appropriate ammunition for the respective game must be used in accordance with the specifications. Please also consider that very few hunting guns are able to fire ammunition of this type without problems.

Any change in bullet guidance affects the point of impact of a bullet. The silencing performance of a silencer also leads to a reduction in the recoil of the weapon. Responsible for this is the special construction of the HAUSKEN silencers, especially in connection with the XTRM mesh. However, the bullet is also slightly affected by the turbulence of the gases within the silencer. With the enormous silencing performance, the point of impact is shifted by a few centimetres. In addition, the uniform repeatability of a shot is optimized due to the significant reduction in recoil. The more comfortable shooting behaviour affects the accuracy of the shooter. After installing a silencer, we recommend checking the shot pattern at a shooting range provided for this purpose. In this way, necessary adjustments can be made and ultimately a fair hunt is always guaranteed!

We base our noise level measurements on MIL-STD-1474D. This is the current standard for measuring the noise level of weapons and/or silencers. This standard specifies the exact procedure and implementation of the test in order to obtain a precise and comparable result. 

MIL-STD-1474D specifies two options for positioning the noise meter (microphone):

1) The first and most important position of the noise meter is at a 90 degree angle, 100 cm to the left of the silencer bore exit. Both the silencer and the noise meter should be 160 cm above the ground. The actual silencing performance of the silencer results from this position.

2) The "shooter's ear" position is a reference position to measure the noise exposure for the user/shooter. The microphone is placed under the same conditions as in the first position, but now in the place of the "shooter's ear" and 15 cm from the barrel axis.
This measurement method does not take into account how long/short the barrel and/or silencer are and will give an erratic result depending on the length of the gun and the length of the silencer. The further the noise level meter is from the noise source, the lower the noise level. As a result, this is not an accurate method of measuring a silencer's noise reduction, but can be used as a reference for the user.

All HAUSKEN silencers are tested and measured in accordance with MIL-STD-1474D and at an angle of 90 degrees, 100 cm to the left of the silencer's exit from the barrel. The quality and regularity of all our sound level measurements are therefore 100% correct.
