Hello, I would like to get advice on the most suitable ammunition for my two inline deringers Gladiator .45 from the Czech company Detonics.
These are modern two-shot deringers. The weapon is designed almost for defense. It has hidden cocks, and switching between barell is mainly done by simply pressing the trigger. The barrel is smooth.
The weapon has overall very compact dimensions.
The deringers that I have differ only in size. The caliber is the same. The barrel of the larger one is 1.5 cm longer (0.59 inch).
With the smaller Gladiator, the distance from the muzzle of the barrel to the piston is only 6 cm (2.3622 inch).
The manufacturer recommends several bullet. I tried all of them. Accuracy is sufficient for a few meters. At 25 meters, however, it is quite a problem to stay in black. Apart from the Harvester sabote, I didn't notice a bigger difference in accuracy with the longer barrel.
I tried:
a) ogival 200 gr.
Compared to others, realistically accurate, yet sometimes it flies unexpectedly elsewhere.
b) real 200 gr.
It rotates differently, losing direction.
c) real 250 gr., maxiball 250 gr.
It rotates differently during the flight, and at 25 meters (82 feet) quite inaccurate. I have this shot loaded for self-defense.
d) a spherical projectile with a cotton pad
The most accurate. However, it seems to me that the bullet is too light. I don't want to use it for self-defense.
d) Sabot Harvester 200 gr.
In the shorter barrel, the bullet is as inaccurate as the real. In the longer barrel is very accurate. Unfortunately, these sabot are very expensive (more than $ 1). I'm also not sure if, in the case of self-defense, passed on all the energy.
I use Vesuvit LC and Vesuvit LC1 gunpowder. Unfortunately, we do not have a very large supply of powder. LC1 dust is intended for small arms, it occurs to me that it burns fast enough.
I tried different weights, due to the method of determination, I stick around 1.5 to 2 grams (23-30 grain).
I'm looking for a shot that would be suitable for self-defense, and at the same time would be accurate enough to 25 meters. I will be happy for any responses, questions, and recommendations. I have to say this modern Gladiator caused me to become much more interested in black powder.
