Hello Folks

I have an Obendorf sporter action, that I've been sitting on for some time, its an intermediate, large ring, small shank, dated 1910.

I was saving it to build a "275 Rigby" on, but I now have a fine Brno 7x57.

Obtaining chrome moly barrels down here in New Zealand has become quite difficult, but I have a line on a good quality 30 cal barrel blank.

If I could think of a suitable 30 cal chambering that is "appropriate" to the action I'd grab the barrel in an instant - but I can't . . . ( beyond 30-06 but I feel the the short mag box of the intermediate might be quite limiting)

Can anyone suggest an chambering that I'm overlooking??

Thanks

Foster
