Thanks Mark.
As long as I can get the cases. But if supply runs out it is nice to know I can form them from something else. (Or simply change the extractor and use Roberts cases - but I like the rimmed cases for some reason).

Well Folks, some feed back. I have just been gifted a Lithgow 250/303 in mint condition, so I am set to go! (From a family of friends).

So my plan now is, the No.I MkI* gets to shoot cast bullets, the No.4 gets to sport a shorter barrel and shoot 180gr RN's for bush hunting and the 250 gets to shoot varmints (and other critters).
