FYI, .223 holes at 200 can be very difficult for a lot of scopes, including Kowa, Lecia, and Swarovski's in the $1K range. Most times we can see them, but if the light is really bad or the mirage kicks up, it'll shut us down.
BTW, I'm talking about looking for .223 hits in black, not another color. Other colors are MUCH easier.
