There are BARs floating around in 9.3x62. Two of them showed up at a local store. The Sauer 303 is another. I don't know if anyone makes new ones...

For folks who want all the bang speed, and a large mag capacity, top up potential, the Winchester 1895 conversion to 9.3 has some adherents. Maybe a Browning lever in box mag, and 30-06 would be another conversion option. These would be street legal most places, no worries about semi. 1895s have been converted to 35 Whelen (not enough), but also various 40 caliber options, since the 405 is so hard to come by.
