Actually, if they are changing seating depth from recoil they would be going variably deeper as they are attempting to stay at rest while the rifle recoils rearward where the front part of the magazine slams into the noses of the bullets. For heavier recoiling rifles and tube magazine rifles I've found the Lee Factory Crimp die to be the best and least expensive way to ensure the bullet doesn't move in the neck- for hard-use, hunting type rounds. Also, I imagine the various magazine designs have to do with reliability of feeding and are all probably a trade off. The other part of tip deformation happens when the cartridge is run up the ramp and into the chamber. Don't have a clue on how to minimize that in a repeating bolt gun :) Was reading not too long ago a discussion by a couple of ballistician/engineer types. They were comparing notes on the effects of bullet deformation and construction on accuracy and ballistics. They stated and agreed that the bullet's base was far and away the most critical element in an accurate bullet along with a very uniform, concentric jacket and core. They also talked about the tip and said something like... the actual tip was not a big factor in accuracy with the spire point bullets but did say that the part of the ogive just behind the tip section was important. None of this is earth shaking revelation, but always interesting!
