Ignoring for a moment the minutiae regarding Pedersen and the effectiveness or otherwise of his designs, really like how you've taken the original and made enough changes to give it the feeling of being sci-fi orientated.
Finally another fan of using actual wood in modern weapons. This actually gives me Dishonored vibes, what would an Whale-Oil Powered rifle look like... And a full stock rifle at that I personally like older more classic aesthetics;
Looks neat. John Pedersen is one of those developers who history tends to shine too favorably on despite his failures. The reality is, he was an idiot. If you look into why none of his designs were successful, it's because they all shared common design flaws despite functioning completely differently. Too complex, an action that's so fast it likes to outrun the magazine, and more. Pedersen kept making the same mistakes over and over again, never learning WHY his designs kept being unreliable and getting rejected.
He worked alongside John Browning. He still didn't learn. He's the type of person who was both brilliant and an idiot. Brilliant because he could figure out these complex ways to make things work. An idiot because he proved incapable of learning from his mistakes or analyzing the basic principles of what was wrong with a given design. An action being a bit too fast for the magazine? Try lengthening the bolt throw to increase its open dwell time. Simple things like this that he failed to consider or adapt for.
And what's even more silly is that he produced MULTIPLE designs that liked to outrun the magazine. He just kept doing it. Keep in mind this was the early 1900's. Spring tempering and metallurgy wasn't nearly as good as it is now. A magazine would only maintain peak performance for a very short time. And thus his designs only worked for a very short time before the magazine could no longer keep up.
Or just implemented something so simple as a delay. It wasn't a foreign concept, either; machine guns often had rate reducers to control their cyclic rate. Something so simple as a popup "speed bump" that slightly slows the bolt's forward travel to allow the magazine time to feed.
Meh, I think you’re underselling him a bit. The Remington Model 10 was a huge success and the Model 17 is practically the blueprint for pump action shotguns to this day. The Pederson device was accepted and mass produced, and his push for the lighter .276 cartridge was absolutely vindicated when the US had to develop an entirely new light cartridge anyways and wound up going into WWII with like three different calibers.
His rifle was a swing and a miss, but it’s not like anybody besides Garand was making anything better.
The Model 10 was a reasonable success for its time, but it was out of production by 1929. As for the Model 17, that was mostly John Browning's work, and it wasn't that revolutionary overall; it was just another manual action and we'd already had lever-action firearms for decades. Lever action is still arguably superior even for shotgun use as it doesn't disrupt your aim as much. Every single design Pedersen had a major hand in was out of production by 1950. The Pedersen Device would have been a colossal failure, as modern evaluations have shown. It was effectively a blowback pistol action that, like all his other designs, had a tendency to outrun the magazine unless the springs were in like-new condition. His .276 rifle also required oiled cartridges. He was a man who never learned from his mistakes or the mistakes of others.
The Model 10 had a production run of over 300,000 guns. That’s more than a reasonable success, it was the highest selling Remington shotgun by far for decades (its replacement, the Model 31, sold ~186,000). Speaking of the 31, it’s also a Pedersen design and was cloned for the Mossberg 500.
The Model 17 is the basis for virtually all of the most popular shotguns used today. There are companies like Ithica that do nothing but make Model 17 clones. It’s cool that you like lever action shotties, but they’re novelty items today.
The Pedersen Device could have jammed every ten shots and would have been a preferable alternative to rushing trenches with a five-round bolt action.
.276 Pedersen only had to be lubricated in the Pedersen Rifle. The Garand was originally chambered in it and didn’t have that issue. The Army rejected it because they didn’t want to make an entirely new cartridge and foul up their logistics, then wound up doing that anyways because .30-06 is just way too big a round.
Like, I dunno man, he was Remington’s in-house designer for almost 40 years and the Army had him on speed-dial, he had his hands in tons of influential designs. He wasn’t some obscure wannabe just cranking out weird designs.
