I looked up some information regarding Kyrie and Rudolf and their positions of Bishops in EP 3 and found the result quite interesting.
"Why is a Bishop called a Bishop?"

The elements of the chess represent the world's societies of the mid of last millennium, especially in Europ & Asia--all of which had undergone the very same system.

The bishops, in today terms, were a bench of politicians gathered to dectate the law & set the norms. But, at that time, the bishops were found falling far short from fulfilling any standard. Frankly speaking, they were two-faced type of men, very manipulative. This is why their movements on the chess board are not horizontal nor vertical, they are diagonal mirroring their snake-like moves.

I could also mention how the Italian Bishop refer to Standard Bearers in the Military and in other Languages to Hunters and Archers.



Also I find this interesting.
00 -

00 buck shell that holds 9 pellets. Buckshot is generally used for two purposes, self-defense and hunting medium to large game. Loads can be tailored through altering the size of the shot, pellet count, length of the shell, powder charge, and in other ways to fit individual weapons and purposes. For instances, loads of 12 gauge, 00 buck are commonly available in 7 to 18 pellets in lengths from 2.75" to 3.5". Reduced-recoil shells are becoming increasingly available. Low-recoil 00 buckshot allows the shooter to make fast follow-up shots, which may be needed in a combat situation. They are also useful for training shooters who are not yet used to the recoil of full-power shells.

45 -

The .45 ACP is an effective combat pistol cartridge that combines accuracy and stopping power for use against human targets.

410 -

.410 bore guns throw the least weight of shot, but are very easy to handle. This results in a very low recoil, so the .410 is often chosen for young shooters

45 and 410 together:
A 410 bore fits into a 45 chamber.

Implying that 45 and 410 everytime they shoot IMO = The gun used is the Winchester 45 Colt with the 410 bore Ammo.
As in:
EP 3: Kyrie and Rudolf were killed by the Winchester 45 holding the 410 Ammo.
Perhaps could imply that Eva shot them with the very gun she killed Battler with or at least:
The person that held the 45 Caliber killed Rudolf and Kyrie.
And it DOES exist as its stated that Rosa used it in EP 2 when she pulverized one of the goats brains.
