Probably the difference is price,is that they think the 30-06 is more popular than 270 so they will get more money for it.??Is this place a browning dealer? Is this a used gun? If its a browing dealer and browning found out he wouldn,t be one for long. The reason that these are the same price and if he is trying to get more he can,but getting less is a no,no with browning people.For they are a fair trade item,and they will take his dealership away. vangunsmith
