[QUOTE="7magcreedmoor, post: 963751, member: 48559"] Here's the short version: Info on your box says 1.4" high at 100 and dead on at 200. Keep in mind this is generic info, your rifle may differ, but theoretically that means there is a 1.33 minute of angle difference between 100yards and 200 yards. Now, that means that if you are zeroed dead on at 100, you'll hit 1.33 minutes of angle low at 200. One minute of angle is 1.047 inches at 100 yards, and 2.094 inches at 200 yards. 1.33x2.094 equals 2.785 inches at 200 yards. Now we can simplify by rounding off 1.047 to just 1 inch per hundred yards, and that is sufficiently precise for most shooting out to half a mile or thereabouts (at one thousand yards the rounding off makes almost a half an inch difference measuring on the target, but is more significant in drop data calculations- you should use true moa for drop charts). You mentioned a small piece of paper. You should have hit between 2 and 4 inches low at 200, aiming at the center of the target. How small was your target? Crunching your numbers for 300 yards, the box info works out to 3.33 moa down from your 100 yard zero. That's 10.477 inches down from your 100 yard zero. For a 7mag, a good hunting zero for deer size prey would be around 250 yards. The drop at 300 would still be in the kill zone, and at short range you won't be higher than the kill zone. [/QUOTE]
