I'll share another example in this thread which is a rifle I recently completed. I started competing in Extreme Long Range (ELR) Competitions in 2023 with a borrowed rifle, and after a year and a half of waiting, I finally have my completed Bat Machine Model L chambered for 375 Cheytac. This rifle pushes 400 grain Cutting Edge Lazers out of the muzzle at 3050fps. I have a 40moa rail with a 20moa mount installed to hold my scope, which, for the time being is a Bushnell XRS II 4.5-30x50mm, which has 32.5mils of internal elevation capacity. The 60moa offset puts me right around 1mil away of the top of my adjustment range, so I have ~31.5mils available to dial for distance. I will shoot matches the most at Spearpoint Ranch in Lincoln, KS, which is one of the world's pre-eminent ELR competition locations - and their monthly matches shoot out to 2913 yards during their regular course of fire. For my particular load, I need 35.3 mils of elevation compensation to reach 2913yards, so having only ~31.5 available, to engage the farthest target, I dial to 30.3mils on my turret, then hold the 5mil hash line in my reticle on the target. So for THESE matches, my scope is really pretty well matched to my cartridge for the distance I need to shoot, and my scope base and rings/mount are well paired to make the most out of my optic.



But... I might still need more than my scope can deliver for some matches. In their March match every year, Spearpoint shoots out past 4300 yards, as do a few other competitions around the country during the season - which would all be far beyond the capacity of my optic alone. For this, I have installed an 18" picatinny rail which will allow me to install a prism device like a Charlie Tarac or Nightforce Wedge Prism (I have an NF Wedge on order), to offset my target view even farther - so moving farther and farther down range, I would shoot out to ~2700 yards by dialing my scope, then moving farther, I would return my scope back to 1mil and install a 29mil Nightforce Wedge in front of my scope, which would match that 2700 yard dial, then continue to dial farther and farther, giving me another 29mils to work with, allowing me to reach ~3600 yards... Adding a SECOND NF Wedge (have to borrow from someone else until I can buy another of my own) in front of the first would stack another 29mils, which would allow me to dial from 3600 clear out past 4300 yards, all without ever needing to hold over in my reticle.

Remarkably, at this extreme angle of line of sight, it's quite likely that I will no longer be able to see my targets in the scope with the rail I have on the rifle at this time, as the ~88mils of angle will mean my scope will be trying to look through the end of my barrel. I may buy a Tacom Delta Periscope prism instead of a second NF Wedge Prism to allow me to look AROUND my barrel to make those longest of shots. But I'll have ~4months or more before I end up shooting that far.
