Yes those that show having them are scammers aka airgunns.com or available across the pond. eBay selling 5mm / 20 cal for @ $100 a box of 500. Unbelievable but it’s here.I must have missed the memo as well .
I have an RX that has needed servicing for awhile now. I always say I'm going to get it fixed, but now looking around at ammo options, I might have to put it up for sale for parts maybe. I do know I have a good amount of pellets for it and if I locate them I will hit you up.
I found one or two other vendors via Google that "says" in stock, but none that I have used or even heard of so buyer beware. Maybe, make some calls and do some research before ordering from any of them if you go that route.
I have always bought my 20 cal at Academy been awhile since the last time
