I did a 35* with a .222 and really like it. Old bench rest caliber.
Longer ago than I care to remember, I had the pleasure of shooting bench rest with a group of pretty fine bench rest shooters (but not against them, lol - I shot Hunter class) and I remember a couple of them shot this new oddball, a .223/35, which also turned out to be a fine bench rest cartridge, just like the .222/35.
