Description:
> Antebellum inserted the 6th chunky .577 black powder cartridge into the cylinder that the earth pony held in her hand. With that task completed, she picked up a steel plate that was pierced with 6 holes that corresponded with the primers on the back of the centerfire cartridges. She lined up the 2 pins on the plate with their matching holes on cylinder and then returned the loaded cylinder to the rest of the pistol. She inserted the cylinder pin/arbor thus completed the reassembly of the revolver. As she did she glanced over at the old earth pony stallion and thought.
>
> Did this pony even read the technical requirements for submissions? This is the opposite of what the Crown is looking for? We're primarily interested in a self-loading pistol, or at least a revolver with automatic extraction and using the new smokeless powder. This thing is doesn't even have an ejector rod!
>
> Still she'd been asked to give the revolver an evaluation, so Antebellum dutifully stuffed some cotton wads in her ears. Then she turned, faced the paper target 25yds away and raised the massive revolver and took aim. Aligning the small blade, front sight with the equally small V notch rear sight she carefully squeezed the double-action trigger. A deep, thunderous roar echoed across the range as the pistol rocked and rolled up in the mare's hand. At the same time a great cloud of smoke hung in the still morning air. By 5th the shot the target was almost completely obscured by a vast cloud of acrid powder smoke. As she sent the 6th and final 400gr/ 25.9 gram soft lead projectile downrange she thought.
>
> Well one advantage here is if you haven't dealt with your problem by the time you've fired the last round you can either use the smoke to cover your retreat, or to mask your presence while you reload.
>
> Having fired all the cartridges Antebellum reversed the process and removed the cylinder and began the task of extracting the now spent cartridge casings with a loose rod. When this chore was completed she reassembled the revolver and then addressed the old stallion.
>
> "Sir. Thank you for taking the time to travel to Canterlot to participate in these trials.Your pistol will be very useful in aiding the Crown in its search for a new side arm."
>
> "Well dearie that's might kind of ya ta say that. If I may ask how will it help the Crown?"
>
> The mare pulled the last cotton wad from her ears and then slightly adjusted her black leather bustier top. Then she replied.
>
> "By being an example of what we're not looking for in a pistol."
>
> "Oh." The stallion said, his face falling.

And I love YOU.
Also, the only real-world .577 caliber revolver I ever heard of was a five-shot Tranter made between around 1868 and around 1891. Articles on the Internet say the cartridge used a 400gr lead bullet—this is around nine tenths of an ounce of metal—and got it up to around 700 feet per second from the revolver's relatively short barrel. I find this implausible. Back in the 80s an American gun magazine staff writer obtained one and tested it. He had to have brass cases custom machined for it. He loaded it with .58" diameter cast lead round balls weighing about 300 grains each. With the cases packed with as much FFFg blackpowder as would fit under a lead ball that size crimped in place, the chronographs said it did 600-650 ft/sec in their tests. A heavier bullet would have occupied more space in the case, reducing available space for powder still further. A 400gr bullet .577" in diameter would have been very short and stubby in its proportions but still would have reduced the amount of powder that would fit in the case. And the cartridge is a very short and stubby one without much internal volume for powder. The powder charge was only 22 or 23 grains with the round ball, which is very light compared to contemporary cartridges. The .44-40 Winchester used a 200 grain bullet, .427" or thereabouts in diameter, and 40 grains of FFFg, giving vastly more velocity than the .577.
