Sierra Load Data

[v2k]

I had went to Sierra's website to get 22-250 load data. It also has 22-250 AI data, the AI data shows less powder and slower than the non AI. That has to be a mistake on their part isn't it. Below are
two of the screen shots I took off of their site. The other loads are like this also.

I find a lot of errors in the Sierra load data

The 22-250 is definitely wrong no way in hell you’re going to shoot a 77-80 grain bullet 3500 fps in a standard 22-250….

The data is correct but the speed columns are not. 22-250 speed column should read 2600 2700 2800 2900 3000 3100 & 3200.
