I. PRESS-RELEASE
DEVA-report proves undoubtedly:
Destruction of the Rifle was due to inadmissible, extremely excessive gas pressure.
Due to a shooting accident in January 2004 near Koblenz / Germany and partial misleading reports, speculations occurred in the recent past concerning the R93, to which Blaser Jagdwaffen GmbH issued on January 26th their opinion on this matter.
In the meantime the experts' report from DEVA-Institute (Deutsche Versuchs- und Prüfanstalt für Jagd- und Sportwaffen e.V.), ordered by the Public Prosecutor, has been received and we have been informed on its content.
The experts' report rules out any faults regarding manufacturing and technical design as well as handling-errors and puts the accident down solely to extremely excessive gas pressure caused by the loaded ammunition.
The destruction of the R 93 was without doubt due to inadmissible, extremely excessive gas pressure caused by the ammunition.
The metallurgical analysis ordered in addition reports moreover that all locking-elements were in perfect condition.
The experts' report proves definitely and as expected the secure
technical design of the Blaser R 93.
II. DETAILED TECHNICAL STATEMENT / BLASER JAGDWAFFEN GMBH
As clearly stated in the Press-release, DEVA's report definitely proved the R93's secure technical design.
As there have been recently several attempts from different sides to discredit the R93, we would like to take this opportunity to clear up some major points.
Therefore, please allow us to present you with the technical basics.
1. Concerning the technical design it has to be stressed that the total strength of a locking-system is generally the result of two individual factors which are mutually dependent:
1.1 the stability / solidity of the individual locking-elements of the entire locking-mechanism and
1.2 the dynamic processes during the shot
This definition is of basic validity and therefore independent of the type of action and lockup being regarded.
For the same token it is of mistakable belief that rifles featuring a so-called secondary lockup (for example via bolt-handle) in addition to the primary lockup in the barrel or receiver cannot be subject to a destroyed bolt being pushed out backwards due to inadmissible, excessive gas-pressure (or even excessive gas-pressure in combination with back blast caused by defective cartridge case).
2. Depending on the dimensions of the individual locking-elements, the overall-strength of a lockup-system featuring a primary lockup only, can therefore be way stronger than the overall-strength of a lockup-system featuring both primary lockup in the barrel or receiver plus secondary lockup (via bolt-handle, for example).
Actions featuring multiple lockups do not automatically mean more security.
Therefore it should not be assumed that systems with multiple lockups are identical to "more secure" systems.
3. Besides the locking-lugs being sheared-off it is therefore also possible that in addition the bolt-handle or the corresponding surface in the receiver can be sheared-off due to the above mentioned reasons (excessive gas pressure with or without back blast).
We have long concluded this fact by extensive testing.
As already described in the beginning, in such cases besides the dimensions and quality of the material being used, the dynamics of each individual case (dynamic course of gas pressure, peak of gas-pressure, etc.) and the resulting strain on the different locking-elements have to be taken into consideration.
The whole process is extremely dynamic, i.e. the rise in pressure only lasts 0.5 milliseconds and the entire dynamic process only about 2 - 2.5 milliseconds.
The dynamics of extremely excessive gas pressure can lead to results which differ significantly from static calculations of "normal" gas pressures, e.g. in controllable spheres.
As a sumup, the results of inadmissible, excessive gas-pressure are of highly individual and complex nature.
In other words: Extremely simplifying assumptions, calculating with static pressures in controllable spheres are totally inappropriate.
They should therefore neither be consulted for unobjective influencing nor in order to reassure oneself…
What does that mean for our R 93?
The R93's massively designed surface of the collet-spring lockup-area as well as the use of scientifically proven state-of-the-art materials ensure maximum strength under massive dynamic forces.
This not only prevents failure exceeding the maximum allowed gas-pressure of the cartridge (Pmax), but even gas pressures that are significantly higher than the proof-pressure realized by the State Gun-barrel Proofhouse.
Not yet mentioned is the R93's secondary lockup, the so-called camplate that supports the locked action against a hardened steelplate in the rear part of the magazine-box.
These engineering principles as well as permanent, extensive quality management all have but one thing in mind: Our customers' safety.
Referring to our introduction and to the DEVA report, our R93 is - after the unambiguous expert's report - a safe rifle and a sound Blaser product.
Yours sincerely in good hunting
