I agree with you about sticking to realistic defense ranges.
From my non expert layman's common sense thinking:
In an SHTF scenario (for the vast majority of the Patriots): All those thousands of meticulously hand loaded tuned rounds aren't going to do you a damn bit of good once you've fired a shot in anger; you'll be wanted and hunted, hence mobile. And unless you have a safe, secure, reliable logistics support, you're going to be getting your ammo where you can find it.
Better to practice with differing loads from many sources within that realistic defense range and leave the tech craft, the art and science of ballistics to the ones who live it and breath it and make it their craft.

After all, there won't be many "experts" out here wtshtf.
Well done.
That’s a good point there Freebird.
