454-230-RN 4 cavity PB Brass (H&G 34)

Welcome!
      Don’t take this the wrong way, but I’ve always wanted to say this :
    Nyaaah, what’s up doc?!
    Ok, got that out of my system.
    The way it works is if you don’t see what you’re after in the store you go to the “Group buy discussions” topic and try to drum up support for the mould you’re after (just the type, like H&G 34). Once you get ten guys signed up it goes to Active Group Buys where you post an “I want”.
    Unless what you want is in there store but had 0 count. Then you start a buy in Inventory Runs where it only takes 5 good people signed up to get a run.
    So snoop around. There’s lots I didn’t mention. And keep checking the store. Al likes to keep everyone on their toes by stocking a style of mould without mentioning it!
