Filing the tip won't effect the aerodynamics one iota at the distances a .250 will be used. It may represent the ability to use a batch of bullets one has that won't shoot well otherwise. The caveat is that you have to come up with a way to consistently remove the exact same amount on each one. A file trim die is the easiest and quickest.
In reference to a previous statement regarding core construction/weight/hollow pointing, etc. vs. pure length of a bullet: nonsense. It's all about length, period, when it comes to to whether it'll stabilize in a given twist. All the other stuff will obviously effect performance -both accuracy and terminal performance- but not whether the rifling is spinning it optimally or not. HP'ing won't matter a tinker's damn. It'll still be too long.
