I actually saw a few boxes of 22lr today. I'm still.setting pretty well on 22 so I decided to leave them for people that need them. The owner also told me he has 16# of Varget that should be in early next week. BTW it was Lost Creek Trading Post in Marshall, Il.
Saw some 22 tracer bullets yesterday at the show in Shipshewana. Thought about buying some but I'm not crazy about reloading rim fire...Powder seems to be available at every show. Rimfire cases not so much...
Anyway, try Lost Creek in Marshall Illinois. I bought BL-C(2) there a week ago and they are always getting it in. I didn't check for those others as I have some still. Hogdgon items seem to be something they get all the time though.
