Great App, simple and Powerful


It is difficult to make a gun selection with so many options available, many times choice is heavily influenced by tradition or what has been normally done in this field. This app helps challenge that perception and provide quantitative feedback as to what would a different option do in this field.

Great perf selection tool


A very good and easy to use app. Makes it very simple to find and select a charge as well as an easy way to get in contact with the provider. Great job on this.

Really useful app


This a great way to look up shape charges. The app is easy to use and the catalog is very extensive.
