Lot of guys here are just starting out and cannot build the ulitmate LR guns ($3500-5000) with the $2000 scopes. You see a lot of posts on how to set up guns for the 200-600 yard shot.
Here is a basically simple rig that is very accurate out to 600-800 yards or so with no clicks.
Started as a 300 WSM in Rem SPS. Factory barrel was not worth a flip so went with a on the shelf Lilja 1-10 twist #3 at 26 inches. Bruce Baer did his medium sporter thumbhole in butternut (2.5 lbs) Ended up with a PTG bolt , Sako extractor and PTG handle.
Shoots 168 gr Barnes TTSX into little bitty holes with RL17 at 3253 fps. Weighs 8.5 lbs with rifle, scope, sling and loaded. Not a super light but easy carry gun. IMO they work geat on deer and give plenty of expansion along with more than decent BC and accuracy. They are not super high dollar bullets that require a special twist and I can buy all I want from sinclairs, grafs or midway.
Scope is a super clear and bright Kahles 3-9X with the TDS. The TDS is like all ballistic reticles it is designed to work off max power.
Here is the secret though. Get the Exbal program (Nightforce sells it under their name too). It has a reticle tool that allows you to adjust the scope operating power from the max power. You must know the distance in inches between each aiming point at max power. That is the essential element along with an accurate MV. Call the tech dept at Burris, Nikon, Swarovski, Leupold, Kahles etc, and they can give it to you. They all work the same so it applies to any of the ballistic reticles.
In this case I worked the POI for each crosshair at 6x, 7x, 8x and 9x as I only had a 3-9X. Used a 200 yard zero. That leaves me little over 1.6 high at 100, so pretty sure I am not going to miss the deer with that. Used white label maker tape on the side of the stock for durability and easy to see. Damn getting old is crappy.
If you enlarge the pic below you can see the distances for each crosshair at each of the powers. It is accurate reliable and super fast with that thumbhole stock.
I took a deer last year at 450+ yards and it was easy with no clicking. I have tested the system at over 600 and it is dead on.
Now exball allows you to run a different set of number if you go to high altitude, change bullets, MV or zeros.
I have set up multiple rifle/scope combos with varying crosshairs and it always works. I have used Swarovski, Kahles, Burris and Nikons and works like a dream with each.
Joel Russo by the way makes the same stock and he is not a bad fellow even if he gets "bored in a treestand"
