Sorry to chime into this forum after I bailed and moved to Texas due to employment, but I still consider myself an Okie at heart. For anyone who may be in South OK or doesn't mind the drive to Sherman-Denison, TX area, J&S Pawn generally has ammo that many other stores do not. They are a fair price also comparable to what you will find elsewhere. I bought some 22 subsonic Remington there last week and they had a fair supply. You might call them if you really need some and might want to take a Sunday drive. They're open on Sundays but I don't know their hours, maybe 12:00 to 5:00 but not sure.
