Clicks vs. M.O.A.

[Ice-Pick]

Ok, going out of my mind here, been reading and reading and reading and i'm running out of hair to pull.
Found a program that is supposed to do the ballistic calc's for me and tell me the number of clicks, prob. is I don't believe the answers.
If I do the math one way I get a small number 26.992, if I used the program it give me a fairly large number 93, but I believe that a buddy of mine who shot the rifle before i owned it told me around 45 clicks.

For background info . its a .50BMG zero's at 200 that were gonna be shooting at 1000 yds. Scope is Swarovski 1/4 Moa / click.

If anyone reading this has a gift for making this more simple and understandable i'd appreciate a post here or PM, Laff, thanks.

i tried a scenario in a ballistic program i use and with a 750 grain bullet doing 3250 at the muzzle it suggests 17.45 moa so if im right and i hope so thats 70 clicks can you post info on your ammo for example ballistic coefficient bullet weight velocity

I made some assumptions here and ran some numbers through an online ballistics program (eskimo.com/~jbm/ballistics/traj_basic/traj_basic.html) just add the www and you are there.

The assumptions I made were - 750 Hornady @ 2750, 2.5" scope height above the bore's center line, 80 degrees F, and 80% humidity. I set the altitude at 775'.

According to the program, the bullet drop at 1000 yards with a 200 yard zero is 207". Adding 20 minutes of elevation to your existing scope setting should have you on paper.

Clicks are a mechanical adjustment, not a mathematical certainty. I have a target rifle sight with 1/3rd minute clicks - 3 clicks per minute. Other sights are 1/4, 1/2 and 1 minute clicks. It all depends. The 27 and 45 calculations are close to 1/2 minute clicks. The "come ups" change for each bullet weight and are very dependant on sight radius.

Unless you have to make a cold-barrel zero one-shot kill with your very first shot out of a new rifle, don't sweat the numbers. It is a science, but shooting is also an art.

Thanks guys

Just for the sake of specifics,,,,,
650 gr. Ball , bullet
.51 cal.
2900 f.p.s.
b.c. .7 (so i'm told)
was at range today, kicked up some dirt first but got on target quick.
Marked settings at 1000, had a little too much help getting started and origional settings were lost before I made my notes (d'oh). Doesn't matter though, after shooting out there I don't plan on going back to 100/200 anyways, i'm hooked.
I do have some 750 Hornady's but saving them till i get comfortable out that far, can't afford to waste em as I can't get more right now.
