These are very much of interest to me, I love all the pre 1945 rifles chambered for the “modern” for the time cartridges, 5.6x61, 6.5x68, 8x68, 7x73 etc. They seem to be a bit scarce, I don’t see many pop up, so I’m wondering if anyone has examples to share as I am trying to study them, makers, barrels, features etc. Of all of those listed, 5.6x61 rifles seem to be the most prevalent, it’s an earlier cartridge for one, so that makes sense. Some of these cartridges became popular later on of course, in the 1950’s and 60’s but these early ones are all too interesting IMO. Merry Christmas everyone.
