Yes. None of the local gunshops ever have in stock what I need. Some may stock Woodleigh bullets now. But the usual suspect calibres only usually. Doubt .423 bullets would be in stock. None stock Bertram brass or bullets to my knowledge?

Telephone them and try to buy by phone. I don't know anyone with a decent online selling site, in Australia, selling either. Anyone know? One seller used to, but relocated to NZ. Too hard to buy from OS.

Both of these guys and businesses support clubs like the BGRC so are good guys.
