I've been thinking about getting one of those Lee hand presses. I think it would be pretty slick for load development. Prep. all the brass, seat primers at home, even load some starting loads at home. At the range after shooting the loads made at home, you could just load a few rounds, shoot them, then load a few more and shoot, ect. You'd only have to bring a scale to weigh powder, the powder, bullets, and the Lee press to seat bullets. The way I've been doing load work up, I load in 1/2 gr. powder increments to a few gr. over book max. I usually stop before I get through all the upper loads so I have to pull some bullets at home, or sometimes I didn't load hot enough so I have go home load some more and make another range trip.
