Sweet rifle!
Howdy!
Calfed, that is a fine rifle! By any chance do the numbers on the barrel match the serial number of the reciever?
While it looks like the location of a barrel mounted scope mount, it would not make sense if there were not another location further down the barrel for another scope mount.
The radius cut in the bolt handle appears to be made to clear a scope, would not make sense to put it there otherwise.
Could it have been a mount for a different type of iron sight? There was one called the Hellquvist that was mounted in about that location if I recall correctly. The book "Crown Jewels" is absolutely invaluable for questions such as these. I gave my copy to a friend who bought most of my Swedes (Pesky recession!) so I do not have access to it at the moment. This is a must have book for Swedish Mausers.
Make it an absolute point to find some of the Swedish surplus ammo that is marked m41, and somewhere on the box will be a word spelled similar to "Prickskytte", this is sniper/target ammo and is VERY precise. I had 2 model 63 match rifles, sadly only 1 now, and both shot WELL under and inch at 100 yards benchrested. And not really benchrested properly either. That ammo is berdan primed. Somewhere on the internet someone figured out the approximate duplicate load. These are spectacular rifles, I have shot sub half inch groups with the aforementioned model 63 rifles. And the CG 80 is supposed to be better.
If that rifle did have Unertyle style mounts on it, it would have to be fun to see what it could do scoped!
Congrats on a fine rifle, enjoy it and please give a range report if possible.
Take care,
Greg
