I mean you're not wrong lol. The market is basically dominated by 4 rounds, not counting revolvers. Those rounds dominate for a reason, they work. If you want balance, go with 9mm. Power while still having high ammo capacity, go 40. And if you just want raw power, 45 and 10mm. All the other calibers are just niche, even if they have pros and cons.

30 super carry really offered nothing new. Even 5.7 offered something new, it's AP ability with the right ammo and the ability to stack a ludicrous amount of ammo, like the 50 round mags in the P90. Kinda sad, competition is good, but it is the way it is.

I feel like having a straight walled 5.7 case of equivalent length would be like a .260-.285, offering the sick capacity of 5.7 but better performance in terms of real use. It'd probably be like a way better .22 magnum that's way more reliable both in feeding and primer ignition.
The 5.7 was made for a barrel at least twice as long as the FN 5.7 pistol, so it's really not cut out for handgun use.

Does someone make subsonic 5.56 in similar spec to m885?
Edit: I guess not(:_(

It's basically gonna be a .22 magnum bolt action but with bullets that don't expand. Good for fucking around, but not much else.
I suggest you get a $10 crackarooski scale and pull some bullets, dumping out powder until you're subsonic. Look and see what the load data is so you'll at least have a ballpark of how much to dump/leave in. You'll probably want to "bracket load" them, doing varying amounts of powder to get an exact speed.

A long time ago even before .300 whisper was known as .300BLK, someone I swear to God made subsonic 5.56 "guaranteed" to cycle your DI factory AR-1., I could swear I've seen this with my own eyes. You take away all the speed from the 5.56 it just becomes a very very heavy copper jacket .22. 70 grains moving at subsonic? Thats less energy than a .380, pointless.

CMMG R&D dept had a hard time just developing a delayed blow back system for 9mm/45. They finally gave up on direct impingement and went with a rotational delay system, that seems to work well, less slam/weight than strait blowback but not as finicky and reliant on gas to drive the carrier.

People always seem to forget when a firearm is designed typically the engineers that build it carefully calculate the weight of moving parts and return springs around the chosen cartridge.

I've seen that for sale and in a video before, there was a company called Silent Strike that made 110gn 5.56. That's double what the barrels are supposed to run, so I imagine accuracy is straight up dogshit because it's probably tumbling like crazy. A side on hit would be pretty gnarly, but good luck hitting whatever you're shooting at.
Idk the foot pounds, but it's less than 147 9mm, and way way less than NATO spec 115 or 124 with a small fraction of the terminal performance. It's somewhere between .22lr and 9mm, closer to the 9 really. Even .300 isn't that great with subs, but it's workable if you need to make shit happen. Stuff like this is interesting, but you probably never buy more than a couple boxes purely for novelty. The purpose behind this is crushed when practicality is taken into account. Not many times when somebody has a suppressor but can't afford a PSA upper and some new ammo that's proven to at least try and be reliable. You certainly CAN run hydraulic fluid in your car engine or change your gender, but you'd be a total retard to do that when cheaper and much better solutions exist. No free lunches as they say.

This shit is all pretty finely tuned and most people aren't smarter than the guys who made the stuff, hence Glock "upgrades and such. People will try and get their .300 builds to "run supers and subs the same with a mag swap" and think they can outthink physics, but in the end they just waste money on dumb shit and deal with short stroking or hella gas and parts wear. Again, the lunch thing

Oh I can run supers and subs in my shorty .300BLK with that mag change. The difference is I re-bored the gas port wider to around .109" or so then put and adjustable gas block. I have OFF if I'm trying to run a strait pull AR, I have X turns for supers and X turns for subs.

he idea someone can engineer a "better" functional round without some giant leap forward in metallurgy, combustible powders or something we have yet to develop it's still the same cartridges.

7.92mm VBR in my LAR Grizzly project gun is very fun. 7.5 FK but even more hipster :)

18.5gr of IMR under a 165gr Hornady .321 FTX projectile at 1300 f/s if a plate burner, yet isn't terrible on recoil due to the .45 Win Mag frame and compensated barrel. i might make a test gun and create some sort of lever delay burst mechanism next year for funsies.

Sorry for being late. That would be interesting though. A 26-28 cal straight walled pistol round. It'd have to be going fast, but I could see it working. It's competition is 25 ACP, and 25 NAA, which wouldn't be that hard to beat, especially if you upped the pressure.

I should have specified a little further, I meant trying to make supers and subs cycle the same with a mag change. There's no way around dealing with the extra energy and face gas of a really overgassed super. And by mag swap, I mean zero change to the gas system too.

I'd imagine so, but the 5.7 case is up for the task as it's rated for 5.56 pressures, so that wouldn't be an issue. You'd probably be able to get somewhat similar power to the 5.7 but with a complete powder burn, so maybe you'd even get a little more in that case.
The 5.7 seems to suck compared to the other main calibers, this'd just be a version that sucked way less while maintaining it's one advantage. It be better than a 9mm in terms of energy per magazine volume, but idk about performance on target. I suppose between 9 and 5.7....

I'd imagine it'd be going slower than 5.7, but the trade would be more mass while still having sufficient speed. That's how it'd have to work given the size of the case. And like you said, better powder burn, since now it's going slower in the barrel, meaning more burn time.

And you'd effectively keep the stacking ability of 5.7 without changing the geometry all that much, so hopefully you could use P90 mags, or at least a very similar knockoff in something like a PCC. I'd imagine pistols would stay the same capacity wise.

I'd be interested though in feeding, since while it'll have that polymer coating presumably, it doesn't have the bottleneck. Wonder if that would affect anything.

I’m worried about how my gun will take the gassing. If I’m not ejecting around 4 to 5 o’clock with a suppressor how can I change that without an adjustable gas block?

The front sight base is pinned currently, I was planning on trying to take it off anyways when my Troy m4 45° offset BUIS arrive. I’m not sure if I can throw a new gas block on a monolithic upper though, can I?

Saving to finally get my PAL (leaf gun license) not going for restricted yet because I haven't had much experience with semi-autos quite just yet to really know what I want, but currently want a repeating rifle, just curious to see what your opinions are on them, I have always thought they were cool regardless of cowboy material.

I don't think you'll find a single person serious about shooting who won't tell you to get a lever action.
They are one of the most reliable, diverse types of rifles out there. Everything from killing squirrels to killing Old Gods that rise from the lakes. And there are millions upon millions of them.
If you want prestige and because you will have fewer guns in your collection, get a classic like a Pre-64 Win94. If you want something with endless aftermarket support, get yourself a Henry. Caliber is up to you, not sure what you're planning on doing. .357 and .44 is plentiful, goes in revolvers to complete the larp, and can even be used to hunt bigger game.
I am partial to 30-30 and 45-70 government, because they are old cartridges and will very quickly problem solve even big-big game.
Even though they are some of the oldest and most plentiful cartridges, there is a cost there. I think 30-30, despite being the first cartridge designed for smokeless powder and being the most popular round for lever actions for about 100 years, is up to $1.25 a round.

Get a tube of silicone gasket maker and make a seal between your charging handle and upper. Cheaper and way more effective than any gasbusting handle I’ve bought. There’s a few tutorials on Reddit for it.

Believe you me, I'm fucking feeling the $1.25 too. And yeah, get a lever-action fellas, very fun and you might be surprised at how well you shoot them. The newer Marlins that are made by Ruger are pretty damn good but they're also charging out the ass for them so it's kind of a monkey's paw rn.

NIGGA!!!
