Re: Bullet seating depth?
The numbers you see in the manuals IMHO are reference, a starting point only. As fare as how deep in the neck should you go? Far enough to hold the bullet securely. The bullet your using is pretty short for cal, so any forces that may push the bullet of of alignment with the center of the case will have less leverage, than a heavier/longer bullet. While seating 1 cal deap is a good idea not all chamberings have a neck that is 1cal long, 2 of the standard long range chamberings have necks less than 1 cal in length.
So experiment with several cases with bullets seated a different depths, by trying to move the bullet side to side, when you find a depth that no longer allows you to move the bullet you can be pretty certain that, that bullet is held securely.
Keep in mind the animals we shoot for food and display are not bullet proof. Contrary to popular belief, they bleed and die just like they did a hundred years ago. Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.
