No matter what a person pays for their loading components, the price of gas and the distance to drive to the range is probably one of the major determining factors of the final cost per shot.
And even the distance that one drives to buy loading components can also be a major contributing expense to the price.
So chalk up some of the expenses to the increased cost for transportation which too often is omitted from the equation.
And of course another unmentioned expense is the cost of membership & fees for gun clubs and shooting ranges.
When those are factored in and averaged out per shot the costs can be astronomical.
And that's not even including the cost of the gun[s].
In the end a hamburger probably costs much less than firing a single shot from a C&B revolver.
