Just an idea for the guys who can't shoot outside. Make it a 5 yard shot on either a 1" dot or water bottle cap. Most people can get 5 yards inside their home or in the garage. It will be the equivalent of shooting a 10" dot at 50 yards. Or even better make it a 1/2" dot which would be 5" at 50 yards or 10" at 100 yard equivalent. What do you think @robbydenning ?
