Blueprints- what do you mean? Who knows who will draw and pull the trigger first? Just the fact that I am holding one can very well scare them off as they don’t know if I have a hair trigger or a 5 lb one…
Just hang up a sign of your most recent target from the range outside your house. Mine will certainly scare them off…
This reminds me… it has been a little too long since I have been at the range….
