You buy packages of the standard primer pick up tubes....I like to take one of the plastic tips and cut off the end so you can use it as an adapter to connect the rf100 tube to the standard primer pickup tube. This helps ensure alignment and prevents you from spilling 100 primers.
When in doubt lay down a towel so if you have a spill you can easily pick them up.
I operate on a if you drop them don't pick them up policy..otherwise you risk picking up spent or damaged primers that are common on the floor of reloading rooms which will make bad ammo or worse jam up the priming system or damaging the priming systems orifice. Which can cause primers to detonate in the system..to clear these jams out need to clear out all the primers which usually ends in more primers being spilled.
