Thread: Tall target test

Perhaps interesting. A film showing how a tall target test can be done, and it also explains why I don't really worry about it.

In my opinion, such a test provides more info about the shooter than the scope.

@Norway

Another Very good video as always and a very good explanation of the tall test.

Cheers

maybe poeple will want to see what Brian Litz has to say on Tall Target Test . . . all information is valuable

You'll have to explain it to me in words of one syllable one day Pete. Unfortunately like most things technical it went right over my head.

I have a very good peaty Islay here that will explain it all and solve the worlds problems by the time we consume it.

You bloody smooth talker Pete. I have never been a pinch hitter but fuck it, it is never too late to switch teams. It's a date. Ha ha ha ha

Iv just done the litz one.
Thomas one seemed a bit over complicated, even tho I'm sure it's all much the same.
Maybe the Mills lost me.

Litz is saying " you must measure things accurately for the test to work".
I am demonstrating what errors you bring into test as it is described.

The end result is that:
1) You can test repeatability on the scope.
2) You can test if the shooter is able to hold the rifle straight.
3) You cannot put a number on the scope tracking (ie measure the size of the scope clicks) because you cannot setup a shooting test precisely enough.

So a tall target test is easy to setup and do, but it will not do all that "internet" says it will do.

Hi Norway .
Could you remedy some of the above problems by :
-measuring your distance with an actual tape
- doing the tracking of the scope from a fix apparatus ( like a picatinny rail bolted to an oak beam or a concrete bench...) and do you really need to shoot your rifle for the tracking test?
- I though canting errors were magnified / really showing at greater distances, like 300 m or beyond..

How do you find the new tactical minox? It seems to be priced almost like a Schmitt and bender but does it really come even close?
I see your mate has a kahles , does the minox match that one as well?

Cheers

How will I get the measuring tape perfectly level? A curve would change the measurement.
Fixed apparatus w/o shooting is the correct way. Not by shooting like internet says.
Camting errors shows up at range due the elevation dialed. You'd have the same angle as long as you dial. (Draw two lines with an angle, the further away from the start the larger the distance between the two lines).

The Minox works. I have no skill or instruments to compare optics.

I agree that shooting a tall target test is a minefield of variables. The first issue, even if your technique and setup is good, is the sample-size, ie how certain can you be of the group centre if you're only firing three-shot groups to measure?

When he is evaluating scopes, Greg Duley has a precise grid on a large board set up precisely at 100yds to determine the turret calibration of a new scope on the rifle which is well fixed down on the concrete bench. Anything less than that, you are probably wasting your time.

I'm going to have to do something like this. My elevation is good out to 700yds, past there I'm shooting high. I'll probably try something like Greg Duley does, but it is an absolute bugger getting everything set up so nothing moves.

Hmmm - watched both, very educational, thanks for bringing the concept to the board . . .

I like that its an actual shooting test, and think that I'll be trying the Litz "method" to gain information. As Rossi pointed out all "information is valuable" as long as you understand enough about its possible variables.

Cheers

Could it be your bc?

Hey Norway, you guys surely have a bit of flat land somewhere in your country? Actually you guys must have some of the best shooting ranges in the world , surely enough there would be one with a proper 100 m targets set up?
