I agree

I didn’t know if I should go full ATN X-Sight 5 at over $1000 (though the instant crosshair adjustments are great) or a rangefinder/ballistic solution would be better that tells you how many clicks or holdovers. I need to look at some more reviews but right now I’m trying to decide between the full scope or a rangefinder or sig sauer kilo binoculars that can calculate and keeping my Athlon scope.
I do have an ATN X-Sight 5 LRF 3-15X and a Thor 5 XD LRF 3-30X. Once I figured out how to set up their ballistic calculators, target practicing became so simple; I just measure the distance, point the crosshairs to the target and shoot. That’s it. No more manual clicks, or holdovers or anything else. The results are extremely reliable. I am really happy with the ATNs.
The problem is figuring out how to set up the ATNs. Ideally, you should be able to enter your projectile’s BC, your scope hight, and pellet speed, and you should be good to go. Well, I was not that lucky.
First, you cannot use the scope hight you measure. You have to find your real scope hight

I’ve started from 26 yards (where the scopes are zeroed, and tested the daystates at decreasing distances, all the way down to 10 yards. I lowered the scope hight a bit if the hit point was above the aim point (and vice versa). In both of my daystates, the measured scope hights were almost 1” higher than the ATN settings (one was 0.9” and the other was 0.8”).
Then I had to adjust the BC. Normally, the manufacturer’s BC should be enough. Well, it turns out, ATN calculates the drop amount using some equations and adjusts them using a look-up table. Unfortunately, they don’t have any data for slow projectiles (pellets /slugs). So, the look up does not work well. To compensate, I’ve tested the daystates starting from 26 yards to 74 yards, at 10 yards increments. If the pellets hit above the aim point, I increased the BC a bit (ATN obviously thought, the pellets should have dropped more). If the pellets hit below the aim point, I decreased the BC by a bit).
At this point, my daystates and I can hit within 1” for distances up to 74 yards, and up to 5(ish) degree elevation change. Anything more than 5 degrees, the spread goes above 1” for distances more than 50 yards. I still don’t know why.
