I don't know where you reside, I'm well out of Ipswich but do most of my shopping at the SSAA owned Queensland Shooters Supplies in West Ipswich, if you're an SSAA member they give a 10% discount, and their pricing is more than competitive.
I use to check into Rebel Gun Works but they've turned too pricey over the last 3 years or so. As an example a Ted Cash brand oval brass Capper priced at $75 a couple of weeks ago, I bought the same thing from Viceroy Books (they have some
Ml things) For $45.
PM me for a reliable and very affordable Black powder supplier, the good German Wano brand stuff imported in bulk. Legal to buy (Firearms license required) and located between Brissy and Toowoomba, worth the drive.
