Looking for the easiest tool to accurately measure base to ogive for bullet seating depth, however would also like the ability to measure shoulder bump for resizing. Bullet to ogive use takes precedence. I have seen a few online from Hornady (used in conjunction with dial caliper) and RCBS which seems like a stand alone micrometer type unit but have no idea as to ease of operation/accuracy. Any advice on a tool that works easily and accurately without breaking the bank would be appreciated.

Thank you
