Training yourself first requires you to know the principle idea you want to accomplish. Whether it is managing recoil, shooting a plate rack quickly or hitting a very small target near or far. It all starts with the principle idea.
It looks like a mess of fun but quite possibly an accident waiting to happen. Separate guns and ammunition. Keep actions open and visible and use chamber flags when you can.
Don’t only ask trainers how questions, ask your trainer why. If the answer doesn’t make sense, keep asking for clarification until it does, or ask someone else who may explain differently.
