Parallax issues

[VeT|Us]

So,
considering buying a Bushnell Banner 1-4x scope.
Most probably would be zeroed at 100 yards, but it says that it's set for parallax at 50 yards. What does that mean in practical terms for me?
Would there be an issue with using a scope set for parallax at 50 yards, at 100 yards?

Need your help, don't wanna waste my money, obviously.

50 yarder is for 22 rf or pistols, theres plenty of 4x scopes around with 100 yd parallax. Parallax is the name given to the function that where you look throuh the scope there is apoint where everything is in focus, cross hair and target and there is no error between where you think your aiming and where the cross hairs are actually aiming. either side of that point the rrors in pointing and focus get greater. Tried to explain it here in straight forward terms not the fancy scientific answer, lol.

Yeah, I believe the Banner scopes are regular rifle scopes, which means the parallax is probably set at 100 yards. So no probs.
