Re: 600 yard scope
If your really asking the question, here is my answer:
"You will be off some, longer the range the more you will be off. Probably fairly little out to 600 yards. I could run my ballistics program and tell you exactly if I had your BC and MV data."
The key is a scope that is repeatable and accurate in terms of clicks and erector movement.
Then develop a "come up chart" in 50 yard increments (50m ?). Do this by shooting your rifle in conditions you expect to use it by shooting at various ranges much like Petander has done with his. Now if you have a range finder like a Leica for spotting and ranging the game, in two seconds you can dial in your scope the appropriate number of moa. Turns out that my .260 varmint rifle for example gets to 550 yards with 11.4 moa and to 300 with about 3.6 moa. If your scope has an accurate mil dot, you can range an 18" high target with the following formula, which is a variation of the W.E.R.M formula, to wit:
500 divided by the mils observed equals the range in yards.
(If it is a big animal you can use the formula for 36" high target of 1000 divided by mils observed is range in yards.)
Accurate Mil dot scopes with good clickers are hard to find, but they are available.
