I just went to the app and selected as shown. The app populated velocity and BC. I didn't change anything the app provided.


Thanks, I kind of pay attention to what you and a few others post but I'm sometimes a little slow... If you were getting those numbers with a 12" barrel vs a 20", I thought I might need to look a little closer.
