Hanco,
Yours would have sold higher if it had a 24" barrel.
That was a lovely rifle.
Hanco's 7mm Weatherby was sort of a rare bird in the evolution of 7 mag hunting rifles,and likely pre dated the 7 Rem Mag.
Back then one of the most famous hunting rifles around was Warren Page's Old Betsy chambered for the 7mm Mashburn Super, which had a 22"(not a 24") barrel. Of course the Weatherby 7mm was also around, but had the drawback of a 12 twist, too slow to stabilize the long 160-175 gr hunting bullets.
The blue print for Old Betsy was as a "mountain rifle",short, with a 22" barrel and weighing 8 pounds or under scoped. The 7mm Mashburn was designed to give a 175 gr bullet over 3000 fps from a 22" ( not 24") barrel. Then, as now, custom rifle people obsessed over blueprints. Likely also why you see so many JOC custom M70 270's kicking around.
But not everybody wanted a wildcat, so sharp rifle builders like Biesen would build a 7mm Weatherby but with a faster 10 twist.....and a 22" barrel to mimic (copy) Old Betsy. I think Hanco's 7mm Weatherby was one of those old customs. I have seen others.
We think of 24" barrels as standard but among some hunters and custom builders this was not always true.
