I usually use the hand press at the range. During load development, I will have all cases prepped and primed. Then set up my harrell's powder measure and throw five charges. Seat the bullet with the hand press and shoot. Gives me the ability to re shoot a group with promise or do a big skip of powder charges if they are garbage. That way I don't have a box of ammo loaded at every .3 grain increments. Also lets me play with seating depth.
