Depends on how much barrel life and how much velocity you want.
Check out the 22br thread. Looks very interesting with a simple size down. Or to juice things up, dasher or gt. Alpha makes 22 gt brass if you’re worried about that.
Just tagging in as extremely interested if you can come up with one for a bolt gun. You’d sell an absolute pile of them here. Wouldn’t take many pieces of lost brass at a match to pay for it.
American reloading has small rifle and pistol primers in stock. I believe free shipping and hazmat too.

I’ve ran my 16” with 55vmax’s to 700 on a 10” plate without issue. I’m Sure I could have gone further, but ran out of light and haven’t revisited it as I generally shoot my bolt guns.
