Be nice Flags, no reason to call BS here - he's not wrong. I've certainly heard of "physics," so I guess I'm your huckleberry...

What happens on paper or on a calculator doesn't matter nearly as much as what happens in the field, so I'll start here: With a 100yrd zero in my own rifles my wife dials 5 clicks on her Savage 300 from 200 to 225, I get 11 clicks with my Rem 300 (1/8MOA clicks). About 3" drop at 200, about 4-4.5" at 225.

Now, taking your advice about checking the calculators out there, I'm babysitting my son and nephew this morning (instead of being in a stand where I belong), watching cartoons, so I took the time to follow your last line and double check my own range cards and see what different available calculators would show:

180gr 300wm at 2950fps with 100yrd zero:

• Litz's "Shooter" app: -2.9" at 200, -6.3" @ 250, estimating more drop on the back end of the 50yrds than the front end, that's easily an inch at 220
• Hornady's site: -3.0 @ 200, -4.6 @ 225
• Handloads.com site: -3.35" @ 200, -4.7" at 220
• Winchester's site: -3.0 @ 200, -4.6 @ 225
• Gundata's site: -2.7" at 200, -5.8" @ 250 - same deal as Litz's app, 3" drop, ~1" in the first half
• JBM Ballistics: -3.1" at 200, -4.3" @ 220
• Berger's site: -3.0" @ 200, -4.2" @ 220

180grn pills at 2950 zeroed at 200yrds:

• Litz's "Shooter" app: zeroed at 200, -2.6" @ 250, that's about an inch at 220
• Hornady's site: zeroed @ 200, -0.9 @ 225
• Handloads.com site: zeroed @ 200, -0.9" at 220
• Winchester's site: zeroed @ 200, -1.1" @ 225
• Gundata's site: zeroed at 200, -0.92" @ 220
• JBM Ballistics: zero at 200, -0.9" @ 220
• Berger's site: zeroed @ 200, -0.89" @ 220

Or you can do it by hand rather quickly, all a guy has to do is estimate time of flight, then calculate the gravitational drop based on that ToF.

Simple math on it - or rather simple PHYSICS on it: 3000fps, 200yrds = 600ft, neglecting any velocity loss, 600ft/3000ft/sec = 0.2 sec ToF. Drop due to gravity is -32.17 feet per second per second, and the formula to calculate non-propelled gravitational drop is = 1/2 * G * ToF^2 (where G is -32.17ft/s/s and ToF = time of fall) = .5 * -32.17 ft/sec/sec * 0.04 sec*sec * 12"/ft = -7.7" total drop at 200yrds. 220yrds = 660ft, 660/3000 = 0.22 sec ToF, .5*-32.17*0.0484 * 12 = -9.3" total drop at 220yrds. So between 200 to 220yrds, that's about an inch and a half of drop. A guy can make a small correction that for 100 or 200yrd zeroes, you'll peak somewhere between 75-125yrds, so call it 100yrds, so the bullet only starts dropping there. So if you cut off the "rise" part of the trajectory, then you get the drop from 100 to 200 and 100 to 220yrds = 0.1sec vs. 0.12sec, yielding -1.9" vs. -2.8" for 200 and 220yrds respectively. Good for about an inch of drop over those 20yrds - obviously, real world bullets slow down in flight, so those ToF's are too short, and the drop would be slightly more. This math doesn't care about zero'd range, only about Time of Fall.

Seems to be pretty much exactly one inch for a 300wm from 200-220yrds, whether you have a 100yrd zero or a 200yrd zero...
