[QUOTE="entoptics, post: 2060681, member: 104268"] Another use for the [URL='https://www.longrangehunting.com/threads/merc-maximum-effective-range-calculator.247929/#post-1966488']MERC Tool.[/URL] Here's the expected deviation at 500 yds with a 0.25 MOA shooter/rifle combo, with 5 fps velocity SD, and 1 ± 0.5 mph head wind (so dead calm to "slight wind") that's switching back and forth from NE to NW in direction. [ATTACH type="full" alt="Screen Shot 2020-12-25 at 10.51.20 AM.png"]236160[/ATTACH] Looks like what you describe. Twice as wide as it is tall... IMO, you're doing pretty good to get sub MOA dispersion at 500 yds. It doesn't take much wind uncertainty to get horizontal stringing... [/QUOTE]
