for basic instructions on how to use and get familliar with a scope go to
Www.ShooterReady.comThey provide a fairly easy guide to follow but you should make sure to take these steps
1) First take the training there is, lol then re take it as its alot of information
2) the first range you go to should be A (there are standard environmental conditions here, which is
what your range card is based on so no environmental data to worry about :) other than wind and range)
This is a good software to obtain howerver you do it (i know it is dl'able but thats dangerous now adays and you shouldnt download games or software this is "cracked" (where the anti piracy part of the software has be removed) because the people who are loosing money to this have a "mis information campaign" going on. What this means is the people who write software or sell a product now adays have started distributing for free their software, but in it is some mean virus'. Although this is illegal, it isnt in the country its set up in and you cant complain you stole a program. :S so it is best to just buy things now adays.
another invaluable tool as a shooter is an exterior ballistics software. These programs are quick and easy to use once your familiar with them and accurate to within 2" over 1800 yards :) (more often your shot will be off because you read the wind wrong)
even if you dont want to "use a computer" to shoot. this software in 2 mins will setup your Range card for the day (as it varies with humidity temperature barometric pressure and elevation from sea level) this means that instead of modifying your 1 range card @ standard atmoshperic conditions with complicated math (taht adds to the error factor) each shot and each day you only have to set up the program with values and it prints a range card w set increments (if you drag your lap top or mini laptop or w/e to the field or range you can use it each shot setting the range as the increment gives EXACT VALUES for the shot litterally ask the computer how to shoot and it will tell you.
Another popular and highly innovative product is the iPhone! it has an app that can be downloaded onto it for like 15$ that is a ballistics software. then, with some precision engineered mounts, its side mounted on the gun and even displays the rifles angle of elevation or depression as you aim!
