dont get any of those, if you wish to target shoot at 100 yds. power numbers on a scope are like this; I have multiple scopes that are 6.24.42
6=lowest visual multiplier setting, such as 6 times as strong or 6 times closer to the target, than your eyesight.
24= highest visual multiplier. with a 18 power or more, you can usually read the
print on the target at 100 yds.
42= the diameter size of the front bell housing on the front of the scope. the bigger the bell you get , like a 50mm or 56 mm, you have to get very high scope mounts, so it won't ride on top of your barrel, or bbl.
the larger the diameter, usually the clearer and more light the scope lets in, which is very important for a clear, bright image.
those scopes you are showing are more for still hunting, squirrel hunting, and such.
if you wanna shoot at 100yards on targets on 1 inch circles, you will want something that goes at least 16 power or higher. you can also get them fixed power, Weaver makes a lot of fixed power scopes, and fix power, because they have few moving parts, are very sturdy. however, the drawback is, you can never go to a lower power, if you need to shoot something up close.
I like the Tasco Varmint series scopes, I have 3 of them, you can get them for 100 bucks or less, and so far they have functioned flawlessly for me.
