[QUOTE="Michael Eichele, post: 500332, member: 1007"] If you are doing your numbers based on a 100 yard zero, your numbers should be correct or are VERY close. This is because if you fired your barrel level straight at a 100 yard target, your bullet would be low at 100 yards. To compensate for it and zero the load at 100 yards, your barrel is tilted up a bit. This is why you will hit 4.1 MOA high at 1000 yards at 90 degrees. Which is why your app show -4.1 MOA. To hit dead on at 1000 yards 90 degrees, your bullet impact would have to be low at 100 yards. In other words, the barrel would then be back to the level position. __________________________________________________________________________________________________________________________________________ If your barrel is 0 degrees pointed straight at a 1000 yard target on level ground the bullet will drop a given amount. In my illustration, it was 300". If you compensate for it to hit dead on and then shoot at a target at the same range 90 degrees above you, guess what? To hit that target you have to undo what you just did. In other words you have to come DOWN 300". I challenge you to input into your phone app a 1000 yard zero at 0 degrees. Then change to 90 degrees. The output inches (high) will be identical to those the same app will calculate for 1000 yard boreline drop (low). One will be a negative and the other positive number but the number will be the same. Make sense? [/QUOTE]
