I don't have CARTRIDGES OF THE WORLD of the world here (the lend and never get back priniple

) but from memory the 7x66 Vom Hofe Super Express was a 404 Jeffery size case but shortened back to about 300 Win length and with more taper than calibres like the current belted magnums and RUMs.

The old handloading book by Phil Sharpe had quite a bit on the older "hot" European calibres.Actually Phil Sharpes book isa agood read as it was written at a time when Wbys were wildcat status and calibres such as the 375 H&H were fairly new on the scene in America and were seen as real cannons. Some of the early Wby claims for ballistics were way over the top
