Can you measure the depth of the bolt face? And the diameter?
what’s the rim thickness and diameter, and what brass are you using(not that this is the culprit)
lastly do you have an old extractor that you don’t mind buggering up? You might be able to cobble something together that would work, depending on what the geometry of the bolt head says.
Back in the day(way back), I welded a bolt head on an old Remington .22 bolt action that had been worn out to the point that it was no longer reliable. Here’s the interesting part. I used a car battery and jumper cables with a finish nail to get the job done. I left the weld proud and then filed it back flush where it was supposed to be.(Still works great) I’m not advocating that you grab the battery out of the grocery getter and go start welding on the bolt head. Possibly though if you need more material on the extractor you could. Guess I should make a disclaimer that anything you do is at your own risk. A .22 LR and a 6.5cm are worlds apart on pressures. one last edit, be darn sure you vent the battery and work in a very well ventilated area...Long jumper cables are advised if you decide to go this route.

one last tidbit, I only used a single battery since I was doing a more finesse weld job than the above video. And as stated make sure you use the positive to clamp to the work piece.
