I might add that most popular would be a 7mm Mauser, how many American manufactures have produced that chamber in mass quantities? Very few.
It used to be popular in the 20s and 30s, but now it's a cult cartridge like a bunch of others that will remain unnamed in the interest of peace and harmony. Most are fine rounds, but have fallen off the radar because they don't sell well enough to make it as regular catalog items. Don't mistake enthusiasm for popularity. Even the nearly identical 7/08, with all the 7x57 wrinkles ironed out, just barely hangs on here and there. Fans of the excellent, but struggling cartridges need to keep their eyes peeled for special runs and other opportunities for scratching their itches.
