On the one side, reloading requires a fairly stiff initial expense, and the space to set up the equipment and store primers and powder, that may make some people nervous. Reloading also requires expenditure of time and effort that you may not have unless you're retired.

On the other hand, you can make cheap ammo that in many cases is more accurate than factory. You can make varities of ammo that you can't buy. You don't actually save money; you just shoot a lot more for the same cost. I started reloading when I was 20 and next year I'll be 80, so I don't think attention to detail is anything gun related. There is the possibility of blowing something up if you make a mistake, and you HAVE to be attentive and do all the little details right. However I've never damaged a gun with the tens of thousands of rounds I've handloaded.
