Thread: Scope tracking

I was with @Puffin when he checked my tract scope, I’m not sure why you would need to shoot any bullets to check tracking.

When shooting at the range we move the point of aim up and down and left and right but aim at the same point this gives us multiple groups on the same target and reduces the chance holes landing in the black lines which can be hard to spot at 200m.

I’ve not needed to and would prefer not to dial when hunting for two reasons one ethical kill and I’m not fit enough to walk to shot animals at long range, if we shot somewhere flatter and can guarantee a clean kill I might be tempted.

I check with a Bushnell collimator over the range of the scope. It is instructive to see the range of tracking error induced by changing the adjustments on a scope, particularly, second focal plane scopes.

What do you mean by this @rupert ?

All mine get checked. my pst2 (4 years old)was 1% out(under) but return to zero has been perfect, hate to think how many times its been dialed to max and back. consistent dialing error is easy to fix.
My ahtlons have been perfect 100% true tracking.
just fitted a delta stryker have only tested the first 15mils but it ok ok far.

Some information can be found here.

quick edit on above post, the 2nd Swaro was Z5 3.5-18x44

Ive never met a Leupold that I have trusted. Although I have a very excellent vx6 2-12 that hasn't let me down - but I don't trust it. Its tarnished by its many pre- deceases.
Does anyone know if Leupold have ever modified or improved their erector systems between models (e.g the various VX iterations)?

@Tahr I was told by a tech at Leupold USA that the older Vx6, such as you have, was redesigned and built sturdier when they brought out the newer VX6 HD line. They all finally have an upgraded dual spring erector system.
So according to Leupold, the newer VX6 HD's are a different beast than the VX6 non HD.

C’mon guys
You know that “without a photo - it didnt happen”
Even those virtual box tests could be backed up wit a pic through the scope and the grid.

Same photos as always: post once and then just provide the link when called upon....

The other face of the white painted bar is marked up with lines spaced at 72.7mm for 2½ MOA intervals at 100 metres.

Tracking test S&B PMII

Full story

Briefly:
100m on 1cm grid
50cm Diamond layout
Shots one at a time on each target in random order, so the scope had been dialled between every shot.

Repeat test a few years (about 1000 rounds) later:

Sorry, I can't quickly see where I first posted this.

Reposting of an old tracking test on a Leupold VX-1 2-7x32



Not nearly as intensive as the tests on the S&B.
100m 1 inch grid
3 shots in middle target to demo grouping
then 1 shot box test 5 MOA on scope scale up right and back.
Shots numberd in order fired. It came back close to where it started.


The another 5 MOA box down and left.
Red marks show where the aiming points were.
The two left hand shots were off the paper but I've marked where they hit.



Within the limitations of so-so grouping, using a modest power scope, it does adjust what it says.

That's a pretty basic tracking test. Its demonstrating great performance over the range of adjustment used for sighting in, which is why this basic scope has been so popular.

I guess if you don't plan to post them you may not have photographed your targets but surely someone else has old ones in a pile somewhere they could put up here and show us ?
