If I know they are coming, which I probly wont, they will be receiving incoming fire from 1/4 mile or more.
You can see a long ways out here in flyover country.
I have a nice 91/30 Mosin which can make those shots, but my old eyes wouldn’t see them out that far even in the prairies. Around these parts it’s hill country. I have a rifle range spotting scope with 50x power. My night vision monocular is 2x and I have a couple of 9x40 for .22 lrs and a bolt 22 magnum. Those 22 rifles can be suppressed very easily when the time comes. Until then, I just store the knowledge in my head. No sense giving fedzilla any excuses.
