Hunters and shooters have traditionally taken up the craft of handloading ammunition in order to mitigate the inherent costs of high volume shooting.
In terms of ballistics and particularly muzzle velocity, the .357 Magnum becomes a whole new animal when chambered in a long gun.
I see a niche for D Dupleks slugs for brush country hunting where ranges are close and conditions do not often offer a textbook perfect broadside shot.
Reducing the length of shotgun shells to 2 inches via handloading, adds ammunition capacity but the increase capacity is only helpful if the ammo performs.
Besides satisfying a curiosity about how these rounds will pattern, there are essentially three practical reasons for loading reduced length shells.
Shotshell reloading is like baking. Stick to the recipe, pay close attention and you’ll get something delicious. Improvise, and the results could be ugly
While I have tried a variety of test media during the course of my ballistic misadventures, I much prefer working with gelatin.
In the days when smoothbore, flintlock muskets were all the rage, crafty soldiers would slip in a few pellets of buckshot to increase the hit potential when firing less than accurate weapons.
Amateur terminal performance testing can provide a great deal of useful information about a load, especially when two rounds are compared side by side.
I’m confident that within its range limitations, any load incorporating the DGS slug would be effective on any North American game animal or attacker.
