Recently I became the proud owner of a 1902 Swedish Mauser in 6.5x55 with all numbers matching.
Shooting this rifle with the iron sights shows very good accuracy potential given the limited real world use with minimum sight setting of 300M.
It has some modifications by previous owners, bent bolt, drilled and tapped with Weaver two piece bases.
I have decided to take advantage of these modifications and mount a scope. With Burris high rings mounted and a Vortex Diamonback 4-12 40mm I set out to the range where I soon found out that even using the lowest setting of the scope the rifle shoots 10+" high at only 25 yards when bore sighting.
What to do next possibly shim up the front ring to get the scope within adjustment range?
Your advice is appreciated.
 
Shim can be snipped out of an aluminum pop can quite easily, slipped under the scope and clamped in place. Make it half an inch wide and an inch long.

You don't specify what ammo you are using. There ARE differences.

And remember: you are sighting-in a rifle at 22 metres, so that adds other considerations.

Shim the brute, then get on target fairly well. Do your final sight-in with the British army method: 2 rounds. You put the first down the pipe, then you take the SAME POA and have a buddy adjust the scope (while you keep the rifle SOLID) until the crosshairs are on top of the bullet-hole. Fire your second round. It should be right on top if you have done everything right. Shooting at a corner of a 4-inch black AIMING SQUARE makes things easy; you can FRAME the edge and bottom of the square, get very precise aiming.

Get some plug screws, too. Some day you might want to re-alter that fine century-old rifle back to what it once was. Three hundred metres was considered NORMAL range back then: that's why that's the lowest setting on the sights. The old-timers would laugh themselves silly if they saw the way we do it today!

Have fun.

Mm has the right idea. I've had some Wierd results sighting in a rifle at 20 too try to get on paper at 50 and 100 too know exactly what you need before busting out the wallet!
 
Smellie thanks for the real world solution its perfect. I will make up a few of these shims and start by placing one under the scope at the front for range testing.

The ammunition I am using is my own brew as follows;
Win brass
Nosler custom competition 140 gr bullets
BR2 primers
36 gr. IMR 4895
COAL 3.056"

When I first tested this neat old rifle using the iron sights I was very pleased with the results it showed very good potential, the bullet printing was way high but tight together. Once I get this scope set properly I would like to print some bug holes from there I plan to refinish the full wood stock and bring it back to its original beauty and simply enjoy shooting at the range.

Cheers,

What kind of bases are you using?
The Weaver equivalent for the M/96 are #46 front and #55 rear.

The rings are Burris Custom Steel ZEE 1", very good point to use the offset inserts these will align the scope while limiting stress, thank you for this suggestion. The Burris website pretty much nails the problem dead on stating that a 0.025" difference between the back and front ring could result in the bullet impacting 25" off at 100 yards. Your sporterized 6.5x55 is a beauty!

The Weaver bases came with the rifle, they are well aligned along the center as the bullets impact right on the center line but hit very high. Is it possible the action is higher at the rear than the front where the two bases are mounted?

I'd like to see a photo of the setup. The rear of the m/96 receiver is lower than the front. The Swedes used a side mount for their scoped m/41 rifles.

I dismantled the setup the numbers on the bases are 46 front and 45 back base they both appear to be Weaver.
I checked further to find there is a big difference in the height of the two bases using the highest point of the action as a reference the back is aproximately 3/32" higher than the front which accounts for the very high point of impact.

I should have checked this prior to mounting the scope, thanks all for your suggestions leading to this discovery.

Next course of action is how to correct this difference should I install a lower base on the back or a higher one on the front?

I have a couple photos of the setup if someone would be kind enough to post them for me.

Then, you have the wrong rear. You need a # 55, what you have is for a LR Mauser (i.e. #45 rear is for the M/98). It will be easy to fix, just get the right one (#55!).
