I always wondered if one of the reasons the Swedish Mausers are so accurate is because they gave them a fast twist to stabilyze those original 160 grain bullets.
Probably something to do with the quality of the barrels, etc. too.
The twist was slightly faster than one turn in 8 inches.
BTW, I would say maybe 90% of Swedish Mausers were made by Carl Gustav and most of the rest by Husquarna. One of my first ones had the Mauser banner and was made by them. No better made than the others but still I have never seen another one made by Mauser.
Gracious! 1 in 8?! Wow. I never knew. That's pretty tight!
I'm sure that materials quality and workmanship had a lot to do with it as well. I was admiring those Swedish Mausers at the gunshop a couple of weeks ago and noticed that they are VERY well made even compared to newer rifles in the rack.
