If you have Gun Log, the new release allows you to enter your own values for the pickers.
The pickers do not have to be used, the fields can be typed into directly. I was just trying to save you all some aggravation trying to type on an iPhone or iPod Touch. It is much easier to type on the iPad. I figured I would take a few hours and type it all in for you all instead of everyone having to do it. Did you notice how many powder types I put in there!
