Reloading is a hobby - I don't amortize my hobby equipment. I find that two hobbies I enjoy using my free time on, bullet casting and reloading, assist another hobby I find very relaxing and enjoyable, shooting. When I wore a badge and was shooting for work related training, I was using their ammo in their firearms.
No need to "amortize" that cost!
To get back in perspective, I live in the middle of nowhere, and gas is $3.75 a gallon. Going to the nearest ammo retailer is a 20 mile round trip. The cheapest 9mm ammo they have there, verified by phone call 5 minutes before I types this, is 50 Federal FMJ for $12, and Winchester 100 round value pack of FMJ for $30, aka $15 per 50. I just finished loading my highest cost 9mm ammo, a 115 grain Remington JHP over a hot load of #7 for a decent SD load if I so chose to do so. This load costs me, according to this site,
http://www.handloads.com/calc/loadingCosts.asp , $8.47 for 50. When I go to my own cast bullets, which I also love using, the costs drops "a bit". $3.20 for 50, to be exact. This allows me to use my limited funds to pay for the fuel to go to the range.
Equipment costs...not very much, a lot of my gear was actually given to me. I have then passed on gear to other starting reloaders. No idea what I've actually spent on real gear, but then again, I don't track what I spend on internet time, technically "wasted time" I could spend flipping burgers. Should I "amortize" my computer, since I am wasting valuable time on it?
I have to wonder how many people would rather go flip hamburgers at McDonald's then have fun with a hobby, if they aren't required to by personal finances? That has to be one of the strangest suppositions I've had the misfortune of reading.
