Can't speak for everyone but most all lefties have, and still do, shoot right bolt rifles. Most continue to do so because not all rifles are availble in LH such as military (Springfields, Mausers, Lee-Enfields, etc.) or vintage (Pre64 M70s). Times are much better now for left hand choices, Ruger just started selling their low price point American rifle in LH. Their M77 is a good solid choice as is a Remington 700. Savage also offers a good selection. A .30-06 is pretty easy to come by from a variety of makers, the 7mm08 will be a bit tougher. A LH stainless '06 is available from Ruger, Savage, Reminton, Tika just to name a few.
