Keith, that's a nice variety of tools. For those not familiar, the flared tubes doubled as a funnel for shot and powder and held paper shells to stiffen them preventing collapse when pressure was exerted on the wads to properly seat them with the two wooden devices pictured as well. From 60-70 lbs. hand pressure was often recommended to seat the wads against the powder.
What prevents the shell from spinning in the tool pictured in the second photo?
