Is there a crimp on bullet style connector for high dc amps? I tried to find one but i guess nobody makes them. Something like 50 amps and 10 awg wire would be perfect for me. I try to avoid soldering because this is a high movement application i need them for and solder makes wire stiff and brittle around the joint. Anderson connectors are close what i want but a lot of people seems to dislike them because wire twist can misalign the pins and cause heat/meltdown.
Are ring terminals bolted together with a wing nut really the best i can get?

Properly crimped ring terminals are definitely the best. I have some 30A connections through soldered connectors similar to your pic and they don't have any issues, but maybe very long term vibrations could fuck them up.

Look into Dinse connectors for welding leads. Way too big for your 10awg wire, but maybe they make something smaller?A Deans connector for R/C stuff is apparently rated for 60 amps continuous and 100 amps intermittent. Maybe look into some other R/C stuff and see what other style of connectors they use.In my experience the Anderson connectors are pretty solid and rugged.What is your exact application?

Why not use something like collet for drill bits. Lots of surface and tight.

Probably not. Most if not all directives/laws/codes for high amp stuff require that the connectors are keyed so that you can’t accidentally reverse polarity.The only connector I can think of that comes close to bullet is the Amphenol industrial for EV charging, Chinese alternative is called zc6 connector I believe but I don’t think they make female connectors, only sockets

picel is the end for tig power cables rated at 150A continuous when gas cooled. standard 3/8 fine thread compatible with brass flare tube fittings to roll your own power block terminal

Does it have to be a bullet connector? Molex makes Mini-Fit Sr. and Perma-seal connectors in 10-12AWG that are rated for 50A/600V.

This is a nth-degree-debunked internet myth.
Crimped connections… at the point of the crimp are a failure point bigger than soldered connections, with the added scarification that the compression ring makes due to the notch sensitivity of the wire. Anybody working on these connectors over the years sees this.
Solder actually helps reduce failures over nicked wires. Whatever you do, don’t nick the wires.
Use heat shink. If you are worried about it, use 3 layers of heatshrink, the first one extending the farthest out from the connection, snd gradually getting smaller closer to the connection point to spread out the stress in both crimped and soldered connections.

Anderson PowerPole go up to 45A. they're stackable and hermaphroditic. very popular in the ham radio world. Anderson make some other connectors that are even higher current

Is a threaded connection a deal breaker? If you wan to get really spendy I would suggest Amphenol Mil-spec, they've got high current connectors in 2 pole up to 150A iirc, you can get them for crimp or solder (crimp tool required) There's even versions with a quarter-turn locking ring instead of the fine thread they usually have.

yes they crimp

Cam Locks. I've wired ones that go up to 800 amps (in parallel)

What did Big Crimp do to you? Not a myth at all and it's easy to verify in practice unless you have never in your life seen a correct crimp. And you certainly have: crimps are the reason factory cables outlast your shitty home-soldered ones. But you don't have to listen, just keep mashing things with your old pliers and soddddering them, and keep busy repairing all your broken shit.
