I'm trying to determine what ballistic software user seanh used in his post on Feb. 11, 2017. He has multiple screen grabs of this software in his post ( see https://www.snipershide.com/shooting/threads/loophole.6253216/ ) but I can't identify the software from the images. If anyone can help that would be appreciated. Also, I'm not sure how to send a message/comment to seanh regrading his post. How would I do that? Additionally, if anyone could direct me to any resources regarding the math/equations of loophole shooting, preferably with real world examples, that would be helpful. Thanks in advance.
