6.5×25mm CBJ

[Rob5]

I found myself reading about the 6.5×25mm CBJ while looking into some unique PDW cartridges, and I realized I don’t know much about it beyond the basics. From what I saw, it’s a high-velocity, sabot-style round, but good information seems pretty rare. Any knowledgeable gentlemen here or know how it compares to the 5.7×28 or 4.6×30?

It's pretty much a "cheat code" for those who love ballistics haha. What's great about the CBJ is that it can fit into any standard 9mm mag and only needs a simple barrel change to operate. Think of it as a handheld railgun, firing a small tungsten dart encased in a plastic sabot at speeds nearing 3k fps. It's absolutely wild.
