Last I heard he wasn't selling anymore? I had a friend who bought from him for years, and towards the end he got stiffed on sending funds and didn't get the pieces he needed. I think things were going bad at the end.
About 6 yrs. ago the original owner sold the business to someone, and there was a thread on Cast Bullet forum stating this. Someone posted the new owner was simply selling out whatever he had purchased, and wasn't buying anything else. So maybe he finally ran out?

I bought several items from Rick, maybe 2-3 years ago, and he always treated me right.  We had some great conversations about loading for the old calibers.  He was actively manufacturing new 310 stuff, and indicated he was very busy.  Maybe he got tired of not having time to shoot?
