That's what we call a "target of opportunity ".The only time it ever bothered me was when I lived in SC and I took my target .223 to a 400 yard homemade range. My target .223 has a NF 12-42x56. I was shooting over a soybean field when I noticed hogs walking through the beans about 75 yards in front of me. Even on the lowest magnification, it took me a few minutes to find the hogs. By the time I found them, they were almost out of the field. I got one of them, but could have got off a few more shots if I didn't have so much trouble locating them.
