While I agree that a small error by itself isnt going to cause a miss, I dont think thats really the entire point. A .2 or .3mil error is more or less the equivalent of 1moa. I had three out of four scopes from “that popular brand that shall not be mentioned” fail, and all were wandering 2+ moa (so more like .6 or more mils). I also had an inexpensive scope from “that other popular brand” that also wandered a similar amount. So the actual error was fairly large, and you have to remember that whatever that error is, it’s IN ADDITION to all the other errors, ie how stable you are, etc. so all it does is take a mediocre shooter and make them worse.
In addition, in all cases the adjustments on the failed scopes werent consistent either, ie on an moa scope you’d move it 8 clicks and you were as-likely to get 1moa of impact-shift as you were 3moa, but very rarely would you actually get the correct poi movement. So zeroing was always a chore and took way longer and more ammo than it should have. This built-in inconsistency also made it harder to see other issues like mounting problems or my own skill. I chased my tail with this for years, when I would have been so much better off (and saved so much $ in ammo) in the long run with a scope that actually worked reliably. I cant say I ever missed an animal because of it, but I can say for sure that I have both missed and wounded animals where in hindsight I think it was a factor.
I do agree with those pushing irons. My eyesight has degraded enough that irons are hard for me now, and since I hunt in the east mostly, I like a little magnification at times to pick a hole that is twig-free, as there’s always brush that I cant see without some magnification and with the aid of the optics. But, if your eyes and your hunting conditions allow, irons are the most reliable option probably.
Heres another good option below, this’d be good on a ML and it’s also not so far outside the OP’s budget.
