Alas, the coming of the .22 Long Rifle rimfire cartridge killed off the old rook calibers, and many of these vintage rifles were rebarreled and reworked into .22s. The advent of restrictive firearm legislation in Britain caused many to be destroyed, while others were exported to Australia, Canada, and South Africa. Historian Donald Dallas estimates the total number of rook rifles made to be in the hundreds of thousands, and while many have gone to their reward, enough are still around to make it interesting at auctions. The old cartridges are a lot of fun to work with, and a ‚Äúbest‚Äù quality rook rifle is something to see. It is also affordable for those who admire English workmanship but can‚Äôt aspire to a big name double rifle.
