I remember reading about a 40 Hart some years back. How does this round differ?
If memory serves me, The 40 hart was based on the 404 Jeffery's (The same case that Remington based there RUM case on), but the rum has a longer case body and a standard magnum case head.
The Jeffery case has a case head diameter of .537 and the RUM is .534, and body dimensions are smaller than the RUM.
I Think ?
