So I'm researching mounts for my JP .308 AR. I'm going to put a Vortex Razor AMG on it. According to Vortex's site, it has 94.5 of total elevation adjustment, but a "max" elevation adjustment of 71 MOA. My first question is how does that work? I don't understand how it has this seemingly random fraction of 94.5 MOA of max adjustment.
The farthest I plan on shooting this is 1000 yards, but it will be rare I shoot that far. Looking at ballistic calculators, it looks a 175grain 308 SMK bullet has about 39.1 MOA of drop at 1000 yards (zeroed for 100 yards). So if I zeroed the AMG center (no inclined mount), I should have ~47 MOA of drop available, right? So there would be no point in having an inclined mount for this setup, as I wouldn't run out of elevation until about 1100 yards, right? I guess my second question is: an inclined mount really only serves a purpose with a scope with less travel and/or much further distances or a greater drop bullet, and in my circumstances, would anyone recommend actually getting an inclined mount or just sticking with a standard mount? |
Your correct in that you don't need a mount with any cant to it. However, I usually buy mounts with cant built in even if I don't need it, mainly because I may sell that rifle or scope, and end up needing it (cant) on the next set up. Basically, just saves another step/expense if I end up changing something. Just something to think about.

Are there any downsides to a canted mount in any situations (other than having to find a specific mount with said cant)? |

There can be in extreme cases, such as not being able to obtain a 100yd. zero. If you stick with a 15-20moa base/mount you shouldn't have any problems, and they should get you out to as far as you want to shoot, with the exception of ELR set ups. Yeah I found some mentions of that, though I assume that was with a scope with less travel. |

Turret design allows expanded adjustment range when L-Tec zero stop feature is disengaged for zeroing purposes. This MOA scope offers 94.5 MOA total elevation adjustment and 65 MOA total windage adjustment. |

Had that issue on a cheap Millet scope. I blamed the scope. |
