Thread: Incremental load test anomalies

Many many things.....
If using an optical chrono take the velocities with a grain of salt. The results are often consistent but rarely accurate. They are good for identifying ES(velocity spread for given charge weights) but average for accurate velocity readings.
Brass prep can effect it variable neck tension clean or carboned up brass plus many other variables.
It really depends how deep down the rabbit hole you want to go.
There are so many things that can all effect velocity and accuracy it really depends what your trying to achieve.
