30/06 as a general rule
*************
The M1918 BAR (a light machinegun) was most commonly made in 30-06, as the gent above me has said. While somewhat rare, they were also made in 8mm Mauser, 8mm Belgian mauser, 7mm Mauser, 6.5, .303 British, and 7.62 NATO. The OTHER BAR is the civilian hunting rifle, made in a variety of calibers from .243 to .300 Win Mag.

Depends on the condition and if you have the original box.
Both the BAR (Browning Automatic Rifle) and the Browning machineguns (series 1919) were made in caliber 30-06. HOWEVER, there were other calibers manufactured for special markets. Search Wikipedia for BAR, and look up some of the secondary calibers- they may be a surprise.
