"Do I need Lube" ? If you don't you'll be sorry..

For bottle neck stuff, I clean, then stand them up on a cookie sheet and lube with Dillon spray lube, ( make sure you get lube inside the neck ) deprime and size, then trim and de-bur, then cleaned & pick the walnut shells out of the prime pockets. Then reload.

Pistol stuff gets cleaned, laid flat on a cookie sheet , a very light
shot of Hornady One Shot, then reloaded.

Rifle stuff, painfully Slow compared to pistol.
