Nukes:

If your ballistics program is accurate to under 1/2 mil @ 600, it is fine. You would have a real hard time trying to figure out what variables are involved and a harder time trying to figure out how much of that .6 M they account for.

You would also have to shoot a lot of ammo under identical environmental conditions to get a statistical sample that has any meaning.

At the longer ranges, seeing becomes an issue with dust, humidity, and other natural obscurants hindering a shooters ability to see well enough for perfect precision. If he is using hold overs, his accuracy lessens. Most of the time he has not measured the distance well enough and unless he is shooting on paper where he can measure shot groups accurately, he can be way off from something that is published. Most shooters have big problems calling their shots and without good, accurate, shot calls, it is almost impossible to figure out what is going on when faced with about any shooting issue.

Many guys shoot on steel and this must be the least accurate way of figuring out a zero. Unless you shoot through paper at a exact distance, and then measure a good statistical sample, you can't be sure what, if anything, is wrong.

Finally, there are a great number of ballistics programs out there that all give slightly different solutions. And, they tend to follow range bands with 500 or 600 being a dividing line with one program for the shorter distances and another for the longer ones.

I wouldn't get hung up over someones ballistics program not being perfect. Use them to get you close and then get your own data.

Thank you.

Maybe I have been spoiled to this point by having the programs agree with each other and also agree with observations within 0.0-0.2 mil.

Thanks again.
