Study 2012: Comparison of the bullet effect of different rifle calibres

Eberswalde University of Applied Sciences - Department of Wildlife Biology, Wildlife Management & Hunting Management

The Killing effect in the game body is created by the interaction of Target effect and Wound effect one bullet and calibre. The target and wound effect in turn depends heavily on the speed and type (StructureThe different types of DDoptics binoculars Binoculars can be divided into two main types according to their basic construction: Construction with roof prism (different types of construction) or with Porro prism. Both designs have their unique advantages and disadvantages. In principle, Porro and roof prism binoculars can offer the same performance depending on the type of glass (BAK 4, crown glass, etc.), the amount of coating required and the manufacturing quality. The details decide whether they are good binoculars or not. " More info) of the projectile.

Against this background, the very interesting question arises regarding the use of Hunting ammunition without lead content. This topic is still very controversial.

What is the target and wound effect with lead-free Ammunition for different weapon calibres? This is precisely the question that this study sought to answer.

Weapons calibre effect study 2012 - comparison of the killing effect of different hunting bullets

Here you will find the Final report "Supplementary investigations into the killing effects of lead-free bullets" the Eberswalde University of Applied Sciences - Germany.

The content of the investigations carried out by the Eberswalde University for Sustainable Development was to examine the effect of different storey structures on different calibres.

The following Rifle calibre were used for the FH Study used:

Based on the results of the study, the experts investigating the study, forestry graduate Carl Gremse and Prof Dr Siegfried Rieger, three requirements for a hunting, Modern hunting bullet from:

1. More than 30 cm linear depth effect
2. more than 100 Joule/cm energy input into the target - this leads to a reliable rupture of the vessel walls along the shot channel
3. more than 1,500 joules of energy contribution within 15cm of meat.

IMPORTANT: The then for the Study still under the Name "Möller KJG" used in the projectiles (IZW study, 2008) go according to more confirmed Information from Sax Munitions GmbH - GF Mr Tobias Büttner on the basic construction of Gerard Schultz (Company GS Custom - South Africa) and were returned in a Co-operation between Sax and Möller developed and manufactured. Sax Munitions GmbH still manufactures these storeys under the Designation "Sax KJG-S". The current stage of development, the Sax KJG-SRis based directly on this storey and represents a Improved further development represent. Möller discontinued this high-quality copper bullet rail in 2010 and now manufactures new ones from brass under the designation MJG (Messing-Jagd-Gfloor).

GREAT SUCCESS: It is remarkable that the Copper hunting bullets (KJG) from Sax (at that time still under the name Möller KJG) even in Calibre .308 are recommended for distances greater than 300 metres with a suitable killing effect (see results table below).

As a result of the investigations, the two gentlemen recommend the following limit ranges for the different bullet types:

Sax Ammunition GmbH defines its Requirements for a modern hunting bullet as follows:

• High precision
• fast and Safe response even with weak game or on Long distances
• High killing effect due to Shock and splinter effect even with bad hits
• large Depth effect to ensure safe rejects
• environmentally friendly Projectile material for people and the environment
• Selection of bullet construction and bullet material for Weapon and barrel-friendly use

Derived from this is the Sax storey requirement:

1. Straight depth effect greater than 0.5m
2. Energy input greater than 500 joules
3. Point 1 + 2 fulfilled up to at least 300m target distance
