Hi I am a retired Customer Service Engineer. I did the 1.3 thing about half a lifetime ago. My interests are enjoying life, showing my 13 year old Grandson the joys of pyrotechnology, and having fun myself getting black powder under my fingernails once again. I have no interest in getting a BATF license or the big stuff again.There is a lot of neat 1.4 material to work with. We are learning to make small mines from scratch and will probably make small shells. I am in the process of making a remote firing system for this next year. Thanks for checking me out Richard
