With ammo shortages and high prices being what they are I have taken to photography to fill in some time in "things" that are of interest to me. To that end here is a photograph of 3 cartridges whose common feature is the diameter of the bullet. All 3 cartridges have their proponents. I happened to have developed a special interest in the .224 Valkyrie because of its ballistics. Perhaps some of you may care to share your thoughts on one or all of these 3 cartridges.
