Like most skills, being proficient BEFORE it is necessary for survival is always a good thing. I know one of the reasons I don't shoot as much as I could or should is because of the cost. Reloading would help mitigate some of that over time.
Brass with a shoulder (rifle ammo), didn't seem all that complex on those videos. It seems about the same as straight-walled brass (HG ammo). Except HG ammo takes MUCH less powder. I would bet the bullets for a 230grain .45acp round cost more than a 75grain .223 round. Am I right? So maybe this balances out in terms of cost per round.
And no, I'm not going to head for the hills if the SHTF. In Portland, there's nowhere to go if there is an earthquake. There are only a handful of highways out of here and each of them go over bunches of bridges. I will be staying here and praying for safety.
