Tom, from left to right here are some 22 caliber wildcats using either 220 Russian or 7.62x39mm parent cases:
22 Pup, 220 Beggs, 22 PPC, 22 Waldog 3
5º, and the
22 Hawk which has a hyperbolic shoulder like the Weatherbys.

Interesting thread, good picture.
I am the designer of the 22 HAWK cartridge. It is based on the PPC case, and features a Wby style double radius shoulder configuration
Keith Francis - JGS, made one of my first reamers for it back in 1986, and I still have the original reamer, gauges, and the spec sheets. It's a great reamer and quite versatile, in that I can run it in .050 long for a superb varmint cartridge, or .100 short for a Waldog style cartridge for benchrest competition. I have various sporter wt. custom rifles, and barrels fitted to some of my benchrest rifles, for prairie dogs, gophers, rock chucks, and even antelope, in the long version.
And, I've used the .100 short for many years in NBRSA BR competition with good success.
Ballistics for the 22 HAWK-L in 26.5 inch barrels:
50 gr. Nosler BT: 3750 to 3800 fps
70 gr. JLK VLD 3250 to 3300 fps
You can push it harder, but these are good performing, trouble free all-weather velocities.
I don't know of many users of it outside of my local area here in Montana. I did send Jim Williams in Georgia, some sample cartridges and specs, as he was very interested in it back when he was actively building rifles for his western prairie dog expeditions.
Also Jim Borden in PA, called me one time about it, as he had a customer who was interested in it. Could possibly have been from my discussing it at the Super Shoot or Nationals.
It is easy, unfussy to load for, not much resizing, long case life, especially with the new Lapua brass. Overall, a very accurate, efficient, low recoil, and fun to shoot cartridge.
