Yes, they have made many BARs in 270
Browning Lever Rifle
I know that Browning made a Greywolf A-bolt rifle in 30-06 because I have one. I don't know if they made any in .270 cal. The Greywolf was only manufactured in 1994 with very limited production. I've heard that there were only 380 made. They are stainless steel with a wooden stock and came with the Browning BOSS attachment.
