I agree with Ned, the use of a ring gage at two more points along the length, combined with the one normally used for seating depth, will flag a change in the ogive well enough to avoid the expense of a profile regression. It was a "shop floor" method used before the proliferation of the more advanced machines.
One tip is to keep the "contact surface edges" of those ring gages pristine to avoid false readings. The hole diameter is important, but the corner break on that hole is also critical when scrutinizing gage forces and errors that it can introduce. You have to apply consistent gage force and keep those edges from damage to avoid confusing yourself.
