Copper versus brass in hunting ammunition - the material discussion of the year 2012
Source: SAX NEWS
According to various publications on the Internet Use of lead-free materials and their alleged toxic alloying elements SAX would like to present its position on this at the end of the year.
With the Efforts to find new and alternative materials to the existing copper alloy, Sax also at the beginning of the year 2010 various trials e.g. with brass as the base material.
Despite the tempting advantages from brass to copper like the Significantly lower material price (approx. 2/3 cheaper than the Sax copper alloy) and the Very good machinability Sax was not tempted to switch to brass for the machining.

Conclusion: The copper alloy is still used for lead-free ammunition bullets
The reason for this is the fact that brass compared to copper also some Serious disadvantages has. For example Brass as a running killer already known and leads to 3-4 times higher running wear compared to copper bullets.
Furthermore Brass too brittleso that, on the one hand, there is already Trains and fields to Chipping on the 1st guide belt, which are pulled through the entire barrel by the subsequent belts and literally grind it out and through Friction welding to the rear guide belts welded on become.
When hitting strong bones despite the presence of grooves that are intended to serve as predetermined breaking points. Chipping on the remaining bolt and thus to the Education from Sloping surfaces. These sloping surfaces have a negative effect on shoulder stability and lead ultimately to Deflections of the residual bolt what was commonly known in the past as Ricochet has made the rounds!
With central hits of the shoulder or hip joint balls, it is even possible to Bursting of the residual brass bolts in several chunks of different sizes.
Analysing all these facts, Sax ultimately stuck with its tried-and-tested copper alloy for safety reasons.
Contrary to rumours to the contrary, this copper alloy, including the chemically bound alloying elements it contains, is absolutely harmless to the environment, humans and, of course, our proud white-tailed eagle. To what extent the approx. 3% Lead in brass Hazardous to health are not to be analysed separately at this point! With this in mind, SAX wishes its customers continued environmentally friendly, lead-free and, above all, accurate and effective hunting with Sax copper hunting bullets.
