Slightly off black powder, 22 hornet brass

[Gussy]

I know someone on here must shoot a hornet. Well, to keep it legal, at least part of the time I'll be using an 1885 Browning.

Now to the question...... I bought a fairly large quantity of once fired WW brass. I'm planning on a full length resize the first time since I have no idea what the original chamber was. From then on, since I'm shooting it, I'll neck size only.

Is it worth it to anneal it?
