I have two 30.06.
An old browning bar with a leupold scope that use with bullets of 165 grains Sierra up to 300/350 meters and a reballed winchester pre 70 ( mauser action) with a Lothar Walter inox barrel 1:12 . I used the 165 graind, but in th epast year and now I used now only Sierra gameking 2160 SPBT at 824 meters/sec ( low velocity do not stabilize the bullet). ad it is accurate up to 600 meters and pheraps beyond
In Italy and in Ungarian last years I shooted 23 caprioli (like a white deer)and 3 daini (like a mule deer ). No one has done more than three steps..
