Found this online today. It came up with the same costs I had calculated but a lot quicker.

Reloading Costs Calculator – Ultimate Reloader
Send me a PM or email and I will send you an Excel workbook that will calculate every caliber you load for pistol and rifle on separate sheets. One sheet is just handgun loads, one sheet just rifle loads, third sheet has blank 'copy and paste' info to make new data blocks. You can copy and paste into a new work 'block', and you can have data for everything.
If I can't remember or have not "data" on what my "stuff" cost me years ago how can I calculate the cost per round?
Why calculate it anyway? It is what it is
If one shoots say 44 Mag
then reloading is way cheaper than buying a box of ammo with XTP bullets!
My 44 Mag reloads easily top $1 each,,,,
but,, it may be obvious,, I prize the value of my labor!!
I never calculated the cost of reloading components,,
the reloading time, to me,, is as entertaining as the shooting.
I do have a 550B Dillon,, that may be part of the reason it is entertaining.
Why calculate it anyway? It is what it is
The powder and primer are fairly insignificant.
Why calculate ? Why not? When someone says "that's pretty expensive to shoot" I say "no, it only costs me X..."
