Home Forums Hunting & Shooting AR and Tactical Rifles 6.8 Ballistic puzzle

2 things about that Jimmy:

- If this is on an AR, your scope height is a lot more than 1.7". More like 2.6-2.7" depending on your mount.
- If you're zeroed (truly zeroed) at 100, you should be ~1/2" - 3/4" low at 50 yd depending on the load.

If your ballistic table is predicting 0.1" difference, that's part of your problem because it's way off. Gotta make sure those inputs are right to get somewhat realistic numbers, but even then you can't trust them until you verify with actual shooting.

With that said, ~1.75" low at 163 yards should be about right, but if your "zero" isn't actually zeroed but off by 3/4" at 50 yards, that accounts for several inches difference right there. Combine that with differences in your shooting platform, and errors start to add up fast.
