I plan on buying a new scope for a new custom build chambered in 243. This will be a top end build so I'll be putting a high end scope on it. On the outside I'll be shooting out to 400-450 meters but the mojority of my shots will stay in the 200-300 meter range. It'll be used for varmit shooting but also punching paper when I can't make it out in the field. So with this in mind, is a scope that's 4-16x enough? or should I go to 25x? Just curios what people think.
