Most any optical scope for 200 to 300 dollars will shoot 100 yards plus just fine. The more expensive scopes will make you be able to do that in Pre-dawn conditions, etc.
Do you have any intentions of shooting before the sun comes up, or after it has gone down? That is where the costs get really crazy is, to make the scope see gather more light to be able to see, while the cheaper scopes won't be able to do that.
Unless you are on a hunt trying to get that trophy, i'd suggest going to any box store and hold each one you like and decide which reticle you like best.
Unless you do your homework and know what each dot means ion a BDC type reticle, they are useless, where a regular + shaped reticle will work just fine.
Also, I prefer something like a 3x9x40 over a 4x12x40 just because of the conditions where I shoot can be pretty thick forests, and something with a lower setting will still be useful in forests, where a larger scope wont be able to focus. if you are just at a range or on an open prairie, a 4x or more will work great.
