Hi :)
In order to familiarize yourself with shooting please go here
I stumbled across this software a month ago as an avid shooter enthusiast. I havent had the chance to fire more than 100 rounds before i touched this and most were iron sights. now i have the math to shoot any bullet in any condition upto 2000 yards :) practically military level training but not quite.
Take the training that is provided and go through it a couple of times there are a few key things to remember
when you first start go to the training range **this range is standard humidity, temperature, elevation, and barometric pressure. This means that all you have to account for is range and wind this is where to start.
1)range the target. see below for details. best to work in yards as sierra is yards too.
IMPORTANT remember if you scope in to 20x to divide your mil dot reading by 2 before your divide the inches x 27.778 or inches x 25.4? this wil give you accurate range (lol get a laser range finder for RL :)
2) Elevation - if your range is 1530yards between 35.6 moa @ 1500 and 36.2 moa @ 1550. use a calculator to determine where your range lies (sierra can be asked when producing a range card to have a set increment if set to the exact range then exact values are given :)
so 36.2 - 35.6 = 0.6 30/50 = 60% to get this divide the range in yards inbetween the increments by the increment value IE in a 100 yard increment it would differ
once you have your elevation dial it in. rounding to the closest 1/4 min of angle.
3) Windage - Windage is a little different in the windage collumn its given in inches of drift per 1 mph wind (if your having trouble with wind take the shot first hit the target read in the bottom wind speed and then calculate that windspeed and get the math first)(use this for range to infact before you delve to far into ranging ( makes for faster learning and can be written of a laser range finder and wind speed measurement accessory which 99% of shooters use now adays unless your some vet or 10000 round pro :S not thier yet)
so take your inches of drift lets jsut say i used the same method to determine the exact inches of drift between the two given (most ranges arent exactly on) and my inches per mph is 3.2 w a 10 mp wind
this is 3.2 x 10 = 32 inches of wind drift total. to conver that to rifle clicks you might remember that 1 MOA is = 1.047 inches @ 100 yards or 1.512.. @ 100 meters that means for every 1 moa you adjust your windage your bullet will travel 1.047 inches for every hundread yards the target is away
FIRST take range 1530 yards and divide by 100 yards to get 15.3 x 1.047 = MOA of windage ON THIS SHOT which happens to be 16.0191 that means for every 1 moa i adjust into the wind it will move 16.0191" per 1 moa i adjust.
Since we know that the wind will blow it 32 inches off target you divide 32 by your Inches per moa 16.0191 to get your MOA windage adjustment of 1.9976... which is rounded to the closest click of your scope (probably 1/4 min maybe 1 min you need to check how many click between the big lines on the gun.
Once you know all this stuff zeroing becomes a matter of how high you gun is over at a certain know distance. :) Sierra has that too :S
SOME THINGS TO REMEMBER
1) Targets height in inches x 27.778 / Mil Dot Reading = Range in Yards
This is where you need to start when taking a shot. The range is the most important factor as it is what the rest of the measurements are based off of. TIP invest in some evironmental accessories something that measure wind speed and direction and barrel, Temperature, Humidity, and get Barometric Pressure.
2) Your "cheat sheet" or "range card" needs to be set up accurately, there is alot of software out there that can do this for you with accurate measurements of your environment (once you get past the math of the shooting it becomes your ability to measure your evironment that makes the shots).
I use Sierra Infinity v6 Ballistics Software :) Found here
its incredibly complicated math that i havent been able to unearth without taking a 600 dollar sniper course, to determine your own range cards in varying environments (humidity and temperature vary from day to day and wil throw your bullets off over 1000 yards)
use this software before you go to the range or as you set up to print yourself the daily range card
then just use the range card and your calcualtor to hit any target you want. youll be able if you bring your laptop or they are shooting a similar load to advise others on how to zero it in :)
3) Your going to need to get some specifics of your firearm and load. the bullet is the most finickey of variables ranging greatly from grain to grain in the same caliber. These data are your bullets Feet per second(this helps determine bullet flight time which decides on bullet drop) and Ballistics Coefficient (a measure of how well the bullets retains its origional velocity against air resistance)(to not slow down)
GL and if you need help converting everthing to meters for the hell of it ive got the numbers :S

If this thrad was helpful please rate it as such
ive been able to track down some specs on your scope
Here is the mounting instructions
Here is simmons catalog that has your scope and some specs on it page 10 and 11
Here is your more exact specs on your scope (this section is the press room and is @ the top right of the sight and kind of hard to see
and FINALLY a place to get your MANUAL! this took a while to find but the responder to this post says hes a dealer that can mail you a pdf format manaul. :) (im sorry but i cannot find it already online for speedy DL) this guy claims that if you give him your Email he will mail it to you (just make a fake email account if your unsure @ hotmail or yahoo or something)
please rate this as fixya :)
NOTE inorder to view a pdf file you need a program that can read them. Adobe is the most prolific but if you dont have it you can download Foxit v3 Build 1560 <--- Here
this is a freeware (free program that anyone can dl for free without breaking any laws) program :)
