How tall is your tall target?

It ain’t that tall! 10 mils is plenty for me!

Getting ready for a run out to the mile range, the prediction for the PRC was spot on at 20.6 mils.
10 x Super sniper delivers again

Yep, 10 mils will do it.

We play around with hunting rifles at a mile and the idea was to see if anything wonky happens at the extreme ends of travel.
Athlon 2-12 on the 243 when dialled to 26 mils (2.6 metres or about 9 feet) was off by about .3 (that takes me to a mile) and vertical was perfect, got to be happy with that.

Why can’t you just shine a light through the scope against a plumb bob and spin your turret? Is it not the same affect?

How do you measure angular adjustment doing that?

I’m probably out of my league here….

The receiver is level, the scope is vertically plum as well. As I spin the turret, the Line on the wall stays plum. What else is there?

I think the point being made is how you know that 10 mrad dialed equals 10 mrad adjusted.

What @Jordan Smith said. Primary purpose of a tall target test is to validate your adjustments move the reticle at the angular value they are supposed to. Plumb tracking is important too but its not the whole picture.

Confirm Your Scope Click Values with Tall Target Test « Daily Bulletin

Have you recently purchased a new scope? Then you should verify the actual click value of the turrets before you use the optic in competition (or on a long-range hunt). While a scope may have listed click values of 1/4-MOA, 1/8-MOA or 0.1 Mils, the reality may be slightly different.

I really like the box 2 bench precision snipershide calibrated 10 mil target.

With flashlight method you can just transfer the MILs onto the wall with a sharpie or tape using the reticle's MIL hashes

And it only works if the flashlight doesnt move at all I think. Not sure how well it would work honestly

Sorry, I get it now.

It certainly can be done, it's just a matter of knowing what to do. If you trust that the reticle subtensions are correct, that method should work.

I would think it would be a little more difficult to detect 1 or 2% errors over 12" of travel vs a true tall target test, but maybe not. It should be a full 1/8th inch for every point it is off

Ill probably give it a go one of these days. Never thought of trying it before this thread

 

[Castle Rock]

I’ve done regular tall target testing before but the point of this test was to run the scopes through the extremes of adjustment as when zeroed at 100 metres out to a mile, ie between 20 and 26 mils.
I did 4 scopes;
Super Sniper 10 x on 6.5 PRC- dialled 20.6 and was exactly 20.6
2-12 Athlon on 243- dialled 26 measured 25.7, about one percent error, will disregard as I can’t shoot the difference
6-24 Arken SJ something 6.5 CM - dialled 25 measures 24.8, again about one percent
6-24 Arken EP something on 223 -dialled 15 measured 14.8, should have been more adventurous but it was time for lunch.


Good to not have to guess or make up

I could probably stand on one leg and play a banjo too…
And get similar results
