I guess your question is a new Searcy for $11,000 (I think) or a used Brit Rifle, similiar caliber. For instance a 450-470.

I would buy a used British Rifle that I would be much happier with than a new anything else. Searcy, Merkel, Chapuis etc.

For that price , today, you could buy:

A John Wilkes 470 with 360#2 barrels. Refurbished in Belgium with European type case colours. In very good condition.

A Jeffery 450#2. Original condition with new leather case. 90%.

At least a hundred 400 3" or 450/400 3 1/4 by various makers, all quality. You would probably get some change back here.

At least two 9.3x74R that were rechambered by Brit Makers from 400/360. Change back here too for a set of Shotgun barrels.
