Time - Virtually a non-issue. Unless you are giving up a money making opportunity or sloughing in your job to do this, your time is worth what you make of it. So, unless you are passing on a task that will put cash or tangible item in your pocket your time is worth nothing in dollars and cents.
Quality - If you do your homework, and follow the instructions you will get equal to better quality. However, there will be a quality upgrade that factory can never produce, and that is matching your gun, shooting style, and shooting sport to the ammunition you produce. Light bullets, heavy bullets, fast burning powder, slow burning powder, hot primer, cold primer, case length, over all length, bullet style, etc. are all things that can be tweaked in hand loading that you will not see from a factory.
Increased Knowledge - The more steps a shooter takes on themselves, the more they know and understand themselves, their guns and their sport. The process of reloading, from research to the actual act, makes for a better hunter, competitor and sportsman.
Money Savings - I have never met a person that saved money by reloading. If they were able to produce the ammunition at a cost savings all they did was shoot more. So, for every percent they saved in cost they increased their volume ... Not a bad problem in my mind.
Enjoyment Factor - In the region where I live we have three seasons - Good outdoor time, cold, cold and wet, and damn cold and nasty. Reloading extends the shooting seasons by allowing me to do something to do with my sport at any time of year. For every shot I shoot I get to spend time sorting and inspecting cases and hulls, I get to reload the ammunition, and I get to package the ammunition. Then there is the journaling of what I have done for future reference. In these times of increased costs this is a way to get more enjoyment for the dollar out of the same dollars - A hundred dollars of factory ammunition provides a weekend of fun, and it is over. However, a hundred dollars of reloaded ammunition provides a weekend of shooting, and a couple weekends or several days of spare time in the evenings reloading and remembering what I did, and thinking about what I will be doing.
In my world reloading is an important part of my sport and my participation in it.
