I messed with a bunch of Swedish Mausers over the last 40 years, from 94 carbines to M96's, M38's, and a shining example of a M41 sniper. Every mother's son of them shot extremely well. Sadly they're all gone now as my interests don't sit still very long. Now my sole 6.5x55 is a Ruger 1A that is truly my heart's delight- it delivers 1/2MOA groups often enough that I'm tempted to call it a 1/2" gun. There's a spare BRNO M98 action gathering dust here that is kind of earmarked to become a 6.5x55, if I feel a need to build yet another totally unnecessary (for me) deer rifle.
Sounds like you had a very nice collection at one time. I believe you when you say you have a 1/2 moa rifle. The cartridge itself is very "inherently accurate". One of the good ones for sure, even though it is damn old.
