Most of you know that when Rick Jamison was working for Shooting Times, he patented a short magnum cartridge. Thought you all might be interested in this photo. The photo is of a 7mm Wade Super Seven on the left, 7 WSM in the middle and .300 WSM on the right. The 7mm Wade Super Seven is listed on page 396 of P. O. Ackley's volume 1 of Handbook for Shooters and Reloaders. The parent case is the .348 Winchester with the rim turned off to make a rimless cartridge. The copyright date in the book is 1962 with my printing being 1977. It sure looks like a WSM doesn't it? Case head diameter is .549" on the Wade Super Seven and slightly less than .551" on the 7 WSM. Overall case length on the 7mm Wade Super Seven is 2.221" with the 7 WSM measuring 2.095" in overall case length.
Maybe Mr. Wade should have been the one to patent the short magnums as he predates Lazzeroni's effort as well as Winchester and Remington's short magnums?
