Loading very close to the lands can lead to pressure spikes. Pressure will decrease as you seat deeper
Read the sticky at the top of this forum
where Berger recommends trying seating at much greater depths than you are talking about
It is very difficult to have a seating depth consistency of +-.002" (IME maybe its just me). If you are seating at .005" off then some could be .003" off and some could be .007" off, if you are very good at keeping seating pressure consistent. If you don't sort your bullets by bearing length, outside neck turn if you are using bushing dies, use expander mandrel, Lee Collets and have a very good hand on exactly consistent neck ID's, then you will have some that wind up touching the lands and some farther off.
For a benchrest competitor with lots of experience, .005" off is completely doable. For a hunter looking for accuracy and safety, not necessary to seat that close.
