Bumping this question for those who are ballistic aficionados.

Toward the end of this next video, he gives a rule of thumb hint if you don't have an ACI.

Thanks. I'll have to find out what the height is. I bet it's 10 feet above the target. I'm told that height is pretty insignificant.

I have a golf range finder that will tell you the compensated range to the flag based on the angle. Its solves the Pythagorean theorem for you. This seems to be the same thing.

Just a helpful tidbit, but you're not zeroed for 200 yards. You're zeroed for 50 yards. You'll be close at 200 but you can only be zeroed for 1 distance.

Now the deviation in impact you're looking for should only be 1-3".

Ok, thanks. Everything I have read is 50 yard zero is the same as 200 yard zero.

edit: I guess 50 yard zero is 200 METER zero. ACK!

Just to be clear on your explanation to him, you can be zeroed for one distance but the bullet could be crossing the line of sight at two different distances; for example, with a 25 yard zero the bullet will cross (intersect) the line of sight at 25 yards and then again cross the line of sight as the bullet is descending some 250-300 yards further out depending, on the bullet weight, velocity, etc.

No I get it. I just thought 50 yards was 200 yards but it's 200 meters. 250ish yards.

How many scopes have a range finder built into it? Seems to me that should be a standard feature on a scope.

For what its worth, the 50 yard berm is actually 46 yards with an adjusted distance of 43 yards.

Better scopes, that have options for different reticules, can be bought with ranging reticules. The range determination is not as precise as a laser rangefinder but they do a decent job for quick and dirty adjustments. There are a lot of variations depending on the manufacturer.

That's not exactly true. The mil-dot can be highly accurate for ranging, if you know how to use the calculation correctly.

Hopefully this dispels the unwarranted notion that ranging reticles are not as precise as a laser rangefinder.
