Some time back I bought a Lee Hand Press because it seemed to fit my lifestyle. (I found it difficult to disappear for a few hours on my reloading bench). Anyway, I've got a range trip Saturday and I had to make about 150 rounds of 9mm. I spent some time out in the hot garage sizing and depriming. From then on I kicked back in front of the TV and hand primed the cases. Thn I used the hand press to flare the cases. I have my powder measure mounted on a board and spent some time charging the powder. Then I used the hand press to seat the bullets and crimp in a different operation
I was a little fumbly to start but I 'learned' how to use it more efficiently in a short while. I think resizing cases would be hard using the hand press, but all of the operations after that are a breeze.
If you think you may want to do reloading bench work away from the bench might think about picking up one of these.
