✅ SOLVED Tiny bullet casing?

[Sirthreadface]

This is my first bullet casing I've found, I don't know much on them and I would really appreciate it if someone could help me out. What company? Type? It has a small D on it.

looks like a CB short.

After some research I found out it might be a 1907 .22 short made by dominion cartridge co. Canada. Does this make sense? (I'm not good with this kind of stuff)

Looks like a CB Cap (the two cartridges on the left in the picture) They are/were used in gallery rifles at carnivals. I had a single shot 22 that I used the CB Caps to shoot dang Red Squirrels (which chew their way into your attic and create havoc). A good close range round

Thanks for the help!
