I am having the chance to build ( with a local gunsmith ) a take down bolt action, I currently own a CZ 550 Medium in 9.3x62 and I also have a barreled action ( just the reciever and complete barrel in fact) from a Brno ZKK 601 in 308 Win,is it a good idea to use the 308 barrel and rechamber it to 30-06 Springfield ( no modification needed on the magazine box,bolt face nor feeding lips ), Since 9.3x62 ammo is really hard to come by here ( 120 US Dollars for a 20 round box of Sellier & Bellots ), the idea is to use the 30-06 barrel for general practice and when hunting Water Buffalo change to the 9.3x62 barrel. Any suggestions, or should I just buy a CZ 550 in 30-06 and leave the 9.3 as is.

Comments and suggestions welcome.

Cheers.

Ernesto.
