Sounds like great performance with all of them.
How far/long did that barrel last?
That rifle was still producing consistent accuracy when I sold it in an effort to work towards a LH bolt action in 6.5x55. It had approx 4000 rounds through it when I sold it. Regular cleaning kept the bore in great shape. And I never let the barrel get too warm by waiting 2 minutes between shots when shooting at the range. The barrel was allowed to cool completely between 5 shot groups. The action slicked up so that I could cycle the action with my thumb, and my left hand never leaving the grip. (Something only possible for a lefty shooting a right handed bolt action.) Spent a lot of time shooting paper and steel out to 400 yards with that rifle. For the first couple of years it wore a Leupold 6x42 scope, then was changed out for a 3.5-10x40 duplex for more versatility for hunting and target shooting. (With a 200 yard zero, holding the duplex reticle where the crosshair thickened on the lower post on target @ 400 yards provided the right holdover.) The factory trigger was set for 3 lbs, and broke cleanly. The rifle was a joy to shoot!
I never pushed the velocities by going over max loads in either the Barnes or Nosler Reloading Guides with IMR4350. Never did try a lot of other powders as the loads with IMR4350 were producing accuracy I was happy with, and others didn't provide any better accuracy in that rifle. I didn't have a chrony back then, or access to one, so I cannot say what the actual velocities were in those two Classics I had. I did play with seating depth trying to tweak accuracy, but in the end, the recommended COAL in the Guides provided best results in that rifle. I didn't have any modified cases, so seating depths were adjusted by adjusting COAL in and out by 10 thou at a time to a max of 50 thou.
Different primers resulted in best performance with Federal 210s. Norma brass was used for the most part...although when I didn't have any, I would use Winchester brass with little if any change in overall accuracy for target practice (did not have to adjust for poi), with full length sizing only for first firings. Reloads were neck sized only. Hunting ammo used new Norma brass only (kept 100 rounds for hunting on hand at all times).
(Picked up a second one with real pretty wood in the early 2000's as I hadn't yet gotten a LH rifle, and was missing not having a Swede to shoot! I shot the same loads in the second rifle. While it too provided MOA accuracy, it didn't shoot quite as well as the first rifle. I didn't shoot it as much before someone else decided they needed it more than I and offered a price I couldn't pass on)
I will always have a soft spot in my heart for the Swede, and my left handed rifles have been/are a joy to own.
Although I did part with my LH Sako 85 Hunter as part of the deal to acquire my LH Steyr Mannlicher Model M FS Special Edition rifle. I have always wanted a factory LH mannlicher stocked bolt action rifle...and now I have one in 6.5 Swede with very pretty wood!
I hope to get out and see how it shoots soon. While I will lose some velocity, it won't be a great loss in a beautiful stalking rifle in the thick bush for deer, bear and moose.
(The Sako 85 produced 0.516" groups @ 100 yards with Nosler 140 gr AccuBond factory ammo.)
A Winchester Low Wall in 6.5x55 is high on the Bucket List! (In the interim, I am really liking my High Wall in 6.5 Creedmoor! It'll go on my next pronghorn hunt.)
