See, what I have a problem with is that in order for a pony to fire that musket he has to stand up on his hind legs, lift the gun to his eye with hooves, and pull a trigger SOMEWHERE without any fingers (and I'm not gonna bother mentioning that any musketeer worth his bullets closes their eyes when firing). And if he wants to hit what he's aiming at, he needs to balance on his hind legs long enough to line of the sights, as well as brace himself for the recoil. Balancing on hind legs is hard enough on a quadraped, doing so while firing a gun is nothing short of miraculous.
I know the Equestria Prevails isn't trying to reinvent the musket just for ponies, he's just drawing cool pictures; and it is cool. I do like the idea of ponies fighting eachother and griffons with shot and powder weapons, but to picture ponies fighting with weapons like spears, swords, and guns (i.e. designed for humans and their opposable thumbs) with hooves (or Celestia forbid, their mouth) stretches my willing suspension of disbelief.
They don't have to stand, in fact laying against the ground is a very good way for them to fire a gun, like human snipers do. The long shoulder grip can be fitted against their torso for steady support, while they hold the front with their left foreleg. With the two points locked down, they can move their right foreleg freely to pull the trigger and reload.
During war, often one group would capture enemy weapons, break it apart to see how it works, assemble it test it, discover it’s weakness, & then rework it to see how they could do better. Plus push necessity (necessity is the mother of all inventions, especially when it is urgent. That said group will eventually come up with something better.
It would be interesting which side will come up with a magazine fed semiautomatic. Their level of technology should allow for them to develop such a weapon, especially the Ponies since they seem to be ahead not only in magic but also technologically. That they were losing initially was because they were never prepared for such a war.
