3,600 yard shot

Hopefully that is my "duh" moment for 2015.

That pales in comparison to your "duh" moment of 2014 where you had mistaken Heather Thomas for Heather Locklear.

Just curious, what kind of range/distance would one start to consider canting a scope instead of mounting level with the bore? I'm sure there are a lot of different variables to take into account.

In my limited experience, I mount everything on a 20 MOA base. Barring extremely unusual circumstances, (maybe never?) if you zero at 100 you'll never have to adjust your POI down, so there is really no point in using a level rail.

That one I felt bad about. The worst part was I was absolutely positive I was correct.

Thats 2700 yds. Now add another 900 yds. to the equation. CheyTac offers 40 MOA base on their rifles, and the author is correct in the addition of ~25 MOA rather than 10-12 as I sated. But this still means one will come up short by quite a few MOA at 3600 yd.

Interesting read follows:



***************************



The most elevation I’ve come across on any scope is 140 MOA, which is the max elevation on the Millett LRS scope. However, that leaves you 56 Minutes short. But mount that scope on a 20 MOA base – which I have on my Savage .338 Lapua -- and you now have a total of 160 MOA – yet you’re still 36 MOA low.

Does Any Scope Have Enough Elevation to Reach 2700 Yards?
Here’s one aspect that the critics have correct – I am unaware of any scope made anywhere in the world with enough elevation to make a 2700-yard shot. Even with a 500-yard zero, the Black Hills projectile will impact 5,311 inches low at 2700 feet. Since one Minute of Angle equals 27 inches at 2700 yards, this means a shooter needs 196 MOA of elevation to hit at that distance. (5311 inches divided by 27 = 196 MOA) The most elevation I’ve come across on any scope is 140 MOA, which is the max elevation on the Millett LRS scope. However, that leaves you 56 Minutes short. But mount that scope on a 20 MOA base – which I have on my Savage .338 Lapua -- and you now have a total of 160 MOA – yet you’re still 36 MOA low. What then? With the LRS scope’s Mil-Dot bar reticle, you can squeeze out another 35 MOA by holding 5 mils over the target. Amazingly, you now are within 1 MOA of that incredible elevation. So, hold just a hair higher – and you have enough elevation! Corp. Harrison, who made the 2700-yard shot, told reporters, “I…aimed for extreme range of the weapon.” There’s no question -- he had to.

I nosed around a little about it, definitely would be better to have than to not have. From what I was reading 0 MOA rail depending on the scope and the round would be good to 600 yards most cases, moving out to 600-1000 needs the 20 MOA. So I agree should just go with 20 from the get go.
