Keep in mind; a lot of those judging Mosin recoil are relatively new to shooting Hi-power rifles. Many have 22lr experience only and were told the recoil is extreme. Proper stance and range time will undoubtedly change their opinion. If someone introduces them to a comparable caliber and shows them how to hold the gun, relax and breath it really isn't extreme recoil. As long as you think it is, it will be. I can't realisticly see much, if any more recoil than .308, 30.06, 8mm. I think my 30/30 has more felt recoil than my Mosins.
"War is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and patriotic feeling, which thinks nothing is worth war, is worse. A man who has nothing which he cares more about than his own personal safety is a miserable creature, and has no chance of being free unless he is made free and kept so by the exertions of better men than himself" John Stuart Mill
