I want one of my rifles that I can shoot at 100 yards. With original blade stamped 0 I am of course way high. So, I took a
suggestion to go with a repro +3.5 and file if need be. Tried this one today. It shoots at the bottom or lower of the target paper.
Even just below the paper of a Birchwood target. I have to sight above the paper to even get it to hit any paper.

Now, using 139 or 140 grain bullets with as issued rear sights I have original blades available from Samco.
They come in the following. -.05, +.05, +.75, +1, -1.25, and +2.0.

Should I be using one of these or a different one to get the rifle to zero at 100 yards? My old eye sight limits my distance shooting.
I am OK to 200 yards at the best it seems. I really enjoy these Swedes,just gotta get elevation where I can live with it. Groups are tight even with Privi!

It sounds like the +3.5 is to high for your rifle. You will want a shorter sight to center your shots in the bull at 100yds. I would suggest that you buy the +1, +1.25 and +2 sights to see which would work best, or you can always just file the +3.5 you have. I'm thinking the +1.25 should work, but it would be good to have several to try.

The 1.25 is a minus though. Choice close would be only +1.0 or +2.0.

I think I would try a +2.0. This should get you fairly close, and if the shots hit a bit low, you would not have so much to file down.

You might also buy a Vasteras rear micrometer sight insert. It is adjustable for moving the zero of the impact area.

I was kind of thinking the same. But have not yet learned the sight parameters yet.
But I sure will find out.

Or you can grind that replacement sight down till its good?

If I had a grinder, I may try. But to hand file it will take a lot of time at the range. Plus, no power for a grinder/ Dremel
at the range. I will probably do as buffdog suggested and get a +2.0. If that works, I will do the same on my other rifle
as well.

I zero my hunting rifles 3 inches high at 100 yards. This gives me a point blank range, for most modern hunting cartridges of about 275 yards, where the bullet trajectory is +3 inches high at 100 and -3 inches at 275 yards. This means that you can aim right at a deer out to 275 yards and you will not be more than 3 inches high or 3 inches low from your aiming point provided you shooting skills are adequate.

Of course, bullet velocity is a big factor. The m/41 Swedish 139 grain spitzer military cartridge has a muzzle velocity of 2592 feet per second in the m/96 rifle and 2510 feet per second in the M/38 short rifle.

Stevan,
Here's some more info that might help you out. Based on my tests with different front sights on an m/96, a change of 0.006 inches of front sight height is approximately 1 inch of elevation change at 100 yards. Using that equation and knowing how high your rifle shoots with the "0" sight blade, you can calculate which blade should be the right one. After you figure it out, let me know, I might have the one you need.

m/96 sight blades (approx .100" wide at top of blade)

#	Height	POI Delta @ 100
-1	0.175"	+7"
-0.5	0.195"	+3"
+/-0	0.215"	zero
+0.5	0.235"	-3"
+1	0.255"	-7"
+1.5	0.275"	-10"
+2.0	0.295"	-13"
+2.5	0.315"	-17"
+3	0.335"	-20"
