I don’t really collect cartridges like the ROOK but the article in JOURNAL #455 by John Pople-Crump caused me to pull out the three I do have. I have always assumed that I had them labeled correctly but now I’m not so sure.
The one on the left is headstamped KYNOCH 300 R&R which I think means ROOK & RABBIT. That’s how I have it labeled. But, it has the dimensions of the cartridge that Mr Pople-Crump calls simply the 300 ROOK.
In the center is a cartridge that I have labeled as a 30-25-150 ROOK but is obviously something else altogether. It is too long to be a ROOK and the bullet is too heavy (150 grains vs 110 grains).
On the right is what I believe is a conventional 300 SHERWOOD.
So, anybody know what I have here?
As a footnote, the JOURNAL article shows a a table from the early 1900s Kynoch Journal that shows the deflection due to a 20 mph side wind at 100 yards. The numbers looked odd to me so I ran them through a modern Ballistics Program and they are only about 1/3 of what they should be. Either a 20 mph wind wasn’t as strong back then or Kynoch has fudged their numbers to sell more cartridges.
