6.5x55 & 7x57. Picked up a like new old purple receiver Ruger 77 in 7x57 a few years back and let my then 14 yr old son convince me it should rightfully be his. Still his favorite and at 18 thinks the old caliber is way cool. He's right. After that I found a 77 MK II in 6.5x55 and to me it's at least as way cool. Both rounds are well over 100 yrs old so guess they qualify as retro.
