I think the depth the bullet is seated in the case has more to do with accuracy than the charge weight or burn rate of the powder.
1) The cartridge oal should be short enough to work through your rifle. Only a single shot is exempt from this requirement.
2) The bullet must not be jammed into the rifling at the leade (then end of the chamber).
3) Some rifles like the bullet real close to the rifling and others want it backed off a considerable amount for the best accuracy.
4) The loa of the longest available bullet will probably be too long for the shortest available bullet, which needs to be firmly held by the case neck.
5) The loa of the shortest available bullet will be too short for the longest available bullet to keep the base of the bullet from intruding on the powder space.
That is enough to start with, and you'll learn more, by experimenting, about how your rifle prefers one or two bullet weights over all the others.
