My notion is that I shouldn’t try shots at critters, even varmints, that I can’t do on paper at the range. I'm pretty good with a 2-or 3moa red dot to 100 yards, but the time I tried it at 200 was not encouraging. I haven’t given up yet, just need to practice. When my Mini 14 trigger gets back from its makeover, I’ll give it another whack using a Romeo 5.
Still, just seeing a fox or yote at 200 without magnification on my hunting grounds is pretty tough, let alone making a good shot on one. Called in close is something else, and I have a FF3 8moa on a Mossberg 590s.
