I will be competing in my first long range high power shooting competition this weekend and need a few questions answered. i'm mainly participating at this one just for the experience, i do not expect to do very good. i haven't actually gotten to shoot at anything over 350 yards yet, but need a little advice before i try. this weekend, the lines fired from will be 500, 600, 800, and 1000. i have done a lot a research up until now trying compute dope adjustments for my remington 700 pss .308win . i use my own reloads firing with a muzzle velocity of 2600 fps. i just have to ask because it just sounds so crazy to me, but am i correct in saying that when using a 300 yard zero, my bullet will drop around 350 inches at 1000 yards. that's what all the tables and charts i use say, but it just sounds so crazy, i mean that's around 30 feet. please give me some pointers or incite if anyone has any. i don't want to look like a total fool when i go out there. i am an experienced shooter, i was a primary marksmanship instructor in the USMC and know a little, but am not familier with the long range high power stuff.. thanks in advance.
It's not just a sport, it is an art form that takes careful development.
I use a standard set of come-up as a base set. For a 308 Win I remember these numbers:
2, 3, 3.5, 3.5, 4, 4.5, 5, 6, 7
These are base come-ups for ranges to 1000 yards beginning at 200 and ending at 1000.
These are cumulative values and must be added to one another as the range increases.
So, with a 100 yard zero I ADD 2 MOA to get to 200 yards. To get 300 yard dope I add 2 + 3 to get 5 and put that 5 MOA value on the scope. At 500 yards I need a "foot" (12 MOA) (2+3+3.5+3.5) of correction.
To get from 300 yards to 1000 yards I'd add 3.5, 3.5, 4, 4.5, 5, 6, and 7 for a total of 33.5 MOA of up or about 335 inches of correction at 1000 yards.
Your post of 350 inches of correction from 300 yards to 1000 yards is about correct.
Thanks for the reply Dave. That helps a lot. So to make sure i have this right, this would mean i would most likely need to to go up about 13 or 14 clicks on a 1/4 moa at 100 yards scope. i'm sorry i sound so ignorant on the subject, but after reading all the stuff i've read the last few weeks about moa and long range shooting, i'm very confused. to me it seemed like if the scope moves 1?4 moa at 100 yards it means it moves 1/4 of an inch at 100 yards. my thinking was that if this is true, then at 1000 yards, the strike of the round would move 2 1/2 inches. if this were true, that would mean i would have to click about 140 clicks up. like i said, i apologize for my ignorance, but i guess this is the best way for me to find out ahead of time.

33.5 X 4 = 134 clicks in a 1/4MOA scope
Each click is 1/4MOA
4 clicks at 100 = approx 1"
4 clicks at 1000 = approx 10"
You need way more clicks than 13 or 14.
14 clicks at 1000 = approx 35"
Keep a copy of Daves numbers for reference it should get you started in the right direction.
OK guys, thanks again for the replies. then i guess i'm pretty screwed then. i use a leupold variX III 3.5-10x50 illuminated mildot scope. i was testing last night, i have it zeroed at 300, only problem is, i only have about 50 clicks left in the up direction before it tops out. so does this mean i'm SOL with my scope?
