If you are carrying the scope into the field along with a rifle, I definitely do not recommend an 80mm scope, unless you have a gun bearer to tote it around - you'll soon come to hate it. A high quality 50mm or 60mm is sufficient for 99% of everyone's needs. Magnification above about 20 in a 60mm will suffer from mirage.
Find a Bushnell Spacemaster, or check out the 50mm entry level scopes at Champion's Choice, Champion Shooters, or Creedmore Sports. Jim Owen at
www.jarheadtop.com has the best prices for Kowa scopes - watch out for gray market scopes from the NY City camera and optics selllers.
Don't buy ultra cheap optics.
.22 holes in black are difficult to see at 200 yards nearly all of the time, the exception when the light is (rarely) just right, even with an 80mm scope. Some shooters put a white reflector (such as a sheet) on the ground in front of the target for illumination. Some have tried reflectors in back of the target on the theory that it will reflect light through the bullet holes.
On the other hand, .22 holes are easy to see at 300 yards and further in a white background - if you are sighting a rifle from the bench only a small aiming point is required, leaving lots of white real estate surrounding. I made up a few target designs with a 1 inch, blue or green square in with a 1 inch grid of lines subdivided into 1/2 inches for load workup at 200 and 300 yards. Without a large black bullseye, I can see the bullet holes and the (thinner) grids at 300 yards.
