Each rifle has its own computer file. In the file besides all the identification information of the rifle, there is a complete list of the range dates, with photographs of the session. Then I list the loads, powder charges, and make note of how they did.

I was going to build a data file for all of these and that way if I wanted to shoot a certain bullet I could pull up loads that I tried and what worked. Each would tell the range date that I could then go back and inspect.

But of course I have not done that yet, so I have to search the file for information when I want to know the load. Once I have SET loads, I enter them highlighted so they stand out more and are then easier to find.
