What kind of MAGNIFICATION range of a spotting scope suitable?

[ShootAndHunt]

I want to buy a spotting scope since I don't want to borrow the range's spotting scope every time, and I might need to use one in the open field besides my binoculars. Could you guys give me some idea what kind of magnification range is suitable for the range and field use? especially the maximum magnification, how much is enough, 20X, 30, 45X, 50X or 60X? My range has 200 Yards shooting position, and I want to see clearly the bullet hole on the target that far. I also want to use this spotting scope in the open field, where the object might be over 1000 Yards far. Given these usage, what kind of magnification range is suitable?

If you think some certain brand of spotting scope is good, could you also share the info with me? I am new to the spotting scopes and really know few things.

Thanks,

ShootAndHunt,

Unfortunately, I have no opinion for you on the power necessary to resolve bullet holes at various ranges. There isn't really a direct correlation between "power" and "resolution," in any case. It's more of a "quality" and "resolution" issue, IMO. An increase in power merely magnifies imperfections, giving a larger fuzzy image.

I use a forty-year-old Kowa, with a 60mm objective, and 20X is fine for 100 yards. I have 45X and 60X eyepieces for it, but seldom use them.

As for learning something about optics, try http://www.betterviewdesired.com/ a birder ("birdwatcher") site, and these folks are passionate about binoculars and spotting scopes. They have years of articles and theory and a person could learn a lot about the subject by reading even the old articles. They rate spotting scopes, and undoubtedly their reasons for choosing one over another will force you to spend lots more than you ever imagined. Stay away from the binocular articles unless you want more binoculars than you can afford.
