About 25 years ago I picked up a Swede carbine at a gun show $60 with Herters dies. Gun had a fair Bishop stock on it. Swede ammo was impossible to find, but you could get (on order) Norma for $19 a box. Since I wasn't going to spend that kind of money on ammo, it took me months of poking through brass at gunshows to scrounge up a single box worth of cases.
Picked up a box of Speer 140gr, picked a load of IMR 4320 right out of the middle of the manual and loaded the box. Fired 3 rnds off the porch to check (and get a rough feel for the 6.5mm Swede, which I had never shot before), then put it away, meaning to get back to it later.
Come late summer, I needed some wood for the winter, and a friend with wood needed a deer rifle. I got 2 cords of wood, he got the rifle and ammo (I kept the dies, he didn't reload). Went out, rolled jacket on the hood of the truck, he shoots 3 shots at 100yds you could cover with a dime. GI sights, no scope.
I have, ever since, REALLY,REALLY regretted trading that rifle BEFORE I knew what it could do.
Today Swede ammo is much easier to get, not really common, but not rare, either. I now have one of the long infantry rifles (dated 1917), and while I love the way it shoots, I'd much prefer the bent bolt handle of the carbine.
With the long rifle (96?), completely original, and a decent 140gr load, you just aim at the 400 meter gong, and unless its really windy, it hits. And the sights adjust UP for distances from there!
