9mm and 5.56 just aren't cost effective to reload for plinking. With the time spent on all the case prep and reloading I could mow a lawn, use the money from that to buy the ammo, and have enough money left over for lunch and a beer.
If you do it just because you like it, I can totally understand that.
The self sufficiency part of it is definitely an attractive point. Stacking it deep when it's cheap is also a good strategy. I bought no ammo from Q3 2012 to Q4 2014, but didn't change my shooting habits very much.
We should all be buying pallets of ammo right now before 2016
Don't get paid for watching TV, but I don't add up the time and convert it to a dollar value either.
I already mow my lawn so that's doesn't apply.
I think people get too caught up in the dollar amount their time is worth when it really comes down to the fact they just don't care for the process of reloading.
