Hah.. Archery with a .22... fantastic!
So it was the primer only .22's that I was forgetting. I've never ventured that route. Actually I have a couple hundred .22 shorts that I haven't even shot.
Right now I love the fact that my old Ruger single six is capable of shooting .22 WMR (with separate cylinder). .22 Stingers. .22 lr. .22 Long. .22 Short. and even the cartridges you mentioned.
I guess that must be it? Probably nothing softer than a primer fired .22 cartridge...
