"...milsurp rifles were those 9mm and 9.3 mm rounds chambered in..." None. They're European hunting cartridges that aren't easy to find ammo or brass for and are expensive when you do.
"...used to load factory 220's in 303..." 215's. I don't think they're still available either though.
"...35 Whelen is 9mm..." It uses a .358" bullet. Makes it a .38. snicker. The 9.3mm X 57mm uses a .366" bullet.
