Re leadfree bullets

Well now.

To my untrained eye, they look like something that Mary Shelley would create if she were to write a book on ballistics.

Anyone any idea of how they performed?
 
I was told they perform like hitting Someone with a baseball bat and knocking them out then stabbing them with a needle in the heart/lungs so they bleed dead. Easy explanation

I assume it is to get weight without the issue of instability through length...seems fairly logical.

Can you translate any of the brochure blurb for us @Bavarianbrit ?

Alan
To bring it to the point, the DSG bullet is a non-deforming design. Much like the Impala from SA it claims to work by means of shock waves.
I wouldn't be concerned about its BC. As I only ever shoot out to a couple of hundred yards, the BC is more or less irrelevant. But the use of a non-deforming and non-fragmenting bullets has proven to be very unreliable, from clean pass-throughs to total devastation.

Discuss, his claims do seem outlandish without a full lab and high speed x ray filming being done.

Mass and dimensionally stable double sharp edged bullet

The lead-free bullets made of copper or brass currently available on the market only function as fragmentation bullets or pure deformation bullets. Splinter bullets made of brass or copper do not solve the problem of contamination and excessive loss of game through splinters and the formation of hematomas

In addition, fragmentation bullets have a strongly fluctuating effect on game strengths, require very high bullet speeds to release fragments and are in the upper range of the permissible CIP firearms gas pressures. Bullet splinters very often destroy the rumen despite being hit in the lungs and penetrate into the rear and vagina area, so that game hygiene is extremely borderline here. In the case of medium to heavy game, large loss of mass of the projectiles due to the fragments released often leads to non full through shots and long escape routes.

With deformation bullets, heavy bullets of medium caliber are often used at hunting distances (80 to 120 m) long escape routes (shot a hand's breadth behind the leg = a full jacket effect) when bones are hit, on the other hand leads to huge rejects, bruises and loss of game.

If, on the other hand, light deformation bullets are used at short distances, the rumen often bursts despite being hit in the lungs, due to the high speed and uncontrolled bullet heads deformation. The rumen contents are drawn into the lungs and the bullets channel by the suction. If shooting at long distances, the flat projectile head breaks the light projectile in such a way that heavy game often leads to non full through shots and long escape routes.

These statements are supported by years of testing different these newly launched hunting bullets on red boar and roe deer in the Taunus / Hessen region of Germany. All game that was shot was processed into the catering industry and could therefore always be examined in detail. From this arose in 2007 the firm with over 30 years of experience in reloading hunting cartridges and testing them in practical hunting operations, a new hunting bullet is born.

"By hunter for hunter"

to develop.

The aim is not to reinvent the wheel, but to combine the positive things of the past with the possibilities and experiences of today for the future.

Construction and effect of the DSG

Our dimensionally stable double sharp-edged bullets are made from a brass alloy on the most modern CNC lathes.

• The DSG does not deform!

• The DSG does not splinter!

• The DSG works through compressive energy.

• The DSG already damages the pressure-sensitive nervous system on the bullet side.

• The DSG retains 100% bullet weight!

• The DSG has a material hardness of approx. 120 HV.

• The DSG penetrates the body of the game in a directionally stable manner.

• The DSG also works when hit behind the shoulder blade.

• The DSG has an aerodynamic projectile tip with a double sharp edge.

Function of the first sharp edge

• It is used to create a slipstream, in which the second sharp edge is located and thereby considerably reduces the air resistance of the DSG.

• Splits bones and so creates secondary projectiles, which the second edge of the sharp edge pulls along, accelerates and displaces over its surface.

• The cylindrical section between the 1st and 2nd sharp edge reliably prevents the bullet tip from bending, even when using Magnum and large calibre cartridges.

Function of the second sharp edge

• The second sharp edge has a surface with a calculated angle. If the DSG hits the body of the game, enormous compression energy is generated by compressing the air, which is displaced via the angular surfaces. As a result, the central pressure-sensitive nervous system, in contrast to all other projectile constructions, is already extremely damaged on the bullet side! (Similar to the effect of the shotguns surface shock)

• The bullet hole in roe deer and red deer is larger than the caliber diameter used, due to the resulting dynamic air pressure and the bullet tip contour, and is always circular and open.

• The compression energy released creates a double, caliber-sized firing channel on the inside of the bullet.

• Vital organs are destroyed by the second sharp edge and the compressive energy released. Secondary projectiles (bone splinters) that arise support this process and allow the game to perish quickly and safely.

• 100% weight retension of the bullet produces an exit wound that is twice to three times the size of the caliper, even with large red and wild boar.

• Little to no hematoma formation, any blood sponges that may develop between the shoulder blades or the chest core can be easily peeled off with a knife.

• Even with strong red deer and wild boar, the body of the game is shot through in a directionally stable manner and produces copious amounts of blood loss on both sides of the beasts escape run (10 to 40 m).

• In contrast to all bullet variants currently on the market, the DSG expends its energy without splintering or deformation, immediately at the moment of impact on the body of the game and not delayed in the body of the game! Regardless of the strength of the game and the range of the shot!

Further advantages of DSG bullets

• Relief grooves on the calibre diameter part of the DSG reduce bullet friction in the barrel, reduces recoil and absorbs deformed bullet material. The barrel is therefore only lightly stressed and fouling is minimal.

• For the reloader the rear edge on the base of the bullet is provided with a bevel to make it easier to place the DSG into the case.

• The DSG can be manufactured in all common but also special calibres. For special calibers, please state the land and groove diameters.

The DSG is patented in its form and function and is produced in Germany!

As a skilled hunter, it is up to you to deprive our critics of the explosive material for negative headlines by doing away with leaded hunting bullets and converting to the modern, lead-free and dimensionally stable DSG hunting bullet.

Because the future has begun.

Do you know if anyone has/does use them over there? The blurb sounds impressive.Real world results would be nice to hear about.

Thank you @Bavarianbrit.

Interesting combination of approach, if you can generate sufficient pressure wave without requiring the opening up of petals to increase the surface area of your piston.

But if the first sharp edge provides a slipstream and reduces the drag on the second sharp edge in the air, presumably it will also do it whilst travelling through the flesh? Seems a tad counter productive...ideally you want to maximise the drag/energy dump into the tissue.

There was a Scandinavian brass bullet which had a wide meplat and worked on a similar-ish principle, can't remember the name but @Edinburgh Rifles were considering offering them at one time...and the wonderfully named Woodleigh Hydrostatically Stabilized Solid dangerous game bullet also uses a broad dished meplat to produce an enhanced piston effect.

Aren't we required to use a bullet that deforms under the deer acts? Hence the special derogation to hold them in years past.

Unless the Deer Act has been amended, then the requirement is that you must NOT use

"Any bullet for use in a rifle other than a softnosed or hollow-nosed bullet"

I'm not sure how those can comply with the law, and they appear to be the same as FMJ

Sadly no, i can open the web page but for some reason i cant view the pictures on my phone.
