Hey KB1, a 22-250 might be fine for 20 oz. soda bottles, but it's not enough gun for those big quart size ones. Tell him to get a 7mm or 300 mag.

Regarding the shooting distance thing, I agree with Spaniel. But remember, he's talking about those who are proficient at long range shooting - and that takes a lot of real time shooting on the range. Thinking you can, and wanting to, and having equipment that can do it is not the same as being proficient at it.
