My Dillon 550 is coming out of a long retirement today.
I ran thru $45 worth of factory ammo in a brief practice session yesterday.
I figure my reloaded ammo's free since the components have been sitting around for years, any accounting method would have them depreciated out by now.
OTOH if you consider the purchase price of components and equipment the cost is a bit higher. To spread out the cost of the equipment you simply load more, that will allow you to buy components in bulk to save even more! Then you get to shoot more, which is the only real benefit of reloading.
So how much will my 45acp reloads really cost? I can come up with a number anywhere from $2-10/box, depending on how I figure it. Beats the heck out of that $22/box stuff I was shooting yesterday!
