@MB Mark suggest you call O'Reilly's Firearms High Street, Thornbury (03) 9480 3366_. O'Reilly's been in the game a long time, use to go there and would be a good start. Note they have an online store (joined up with others).

Good for a browse as a start. There would be second hand presses around but would buy new dies/tools.
