I am having CH4D make some dies for a .224 Donaldson Ace I am building, but in the list of dies they have in their archives they also list a .220 Donaldson Ace. I have a lot of info on Harvey's work but nothing for this cartridge. CH sent the drawing and it is a shortened 220 Swift case from head to shoulder 1.36" (same as .219 Wasp) and overall length of 1.882". The increased case capacity appears to be from the larger diameter of the Swift case. I cannot find any information other than Wilson does list a case trimmer bushing for it.
Anyone know anything about the .220 Don Ace? Looks like someone named it in Donaldson's honor?
