It doesn't matter if it was shot or not if there are rub marks on the sides of the hammer (indicating that the action has been worked a bit) and or there are any marks on the loading gate indicating that it has been loaded. If it has any of these marks or signs of use in the action, a collector will consider it as fired. Therefor, if you are not a collector, than do with it what you bought it for and what it was made for-------SHOOT and ENJOY it!!!!
