the b78 was made for 10 years starting in 1973. they were made with a higher grade of wood, some were extremely beautiful. from my experience( i have 6), they are, as a whole, accurate while some are extremely accurate. the trigger is adjustable. they came with either an octagon or heavyish round barrel. 22250, 6mm, 243, 25-06, 30-06, 7mm mag, and 45-70. they differ from the new high/low walls in that they had nicer wood, the serial number was not crudely stamped on the side of the action, they had a different trigger mechanism, the trigger was not gold colored but silver, and they had a polished grip cap. they are very fine rifles and as reliable as any rifle made.
