Don't know anything about rice oil, but I can tell you I've had nothing but headaches with the hornady one shot. I use a small base sizer on 223 for my ARs and have gotten so many stuck it is not even funny. I've loaded over 10k pieces already and had to the tried and true " rolling hem on the lube pad with regular lube. Am I just an idiot and not using he spray lube correctly? Before you answer-- Be nice.
I think something else is wrong. I use one shot exclusively with my 223 rounds and RCBS small base dies. I have never had a stuck case in many thousands of rounds.
