Interesting rifle with an interesting history. No doubt many an antelope has fallen to its bore. Perhaps some Indian blackbuck and other buck as well. And whatever it was used for in Australia since here.

Hopefully the existing barrel can be returned to use in some sort of classic suitable bore and chambering. A .375/303 if the barrel is thick enough would be great. Maybe a .360/.303. Or a.350/303. Maybe even a .330/303. Of course the .303 itself would be the best if it was possible.
