Sounds like a neat cartridge. For like of a better name, call it a .22 Savage Hi-Power Ackley Improved.Nope, I have a .22 Savage cartridge in my collection. Case body is blown out, with a sharper shoulder. I'll see if I can get a picture up. Shoulder angle appears to be close to 30 degrees.
Rid myself of my Herter's 22-3000 brass, R2 Lovell brass, and R2 dies. I gave my Hervey Lovell 22 Varminter (22-250) to John Holliger. John has a wonderful collection of customs by the old masters. I had a little brass and his dies. Lovell built it for a stockmaker in Texas City, Tx in the 1940s I believe. I had the correspondence between the two, And it went with the rifle.Landis mentions in his 1946 book, Twenty-Two Caliber Varmint Rifles , Charles C. Johnson developing a 22-35 wildcat . 30-30 cases could also be used.
