For jacketed, I use a Hornady cam lock. For lead, I use an
RCBS but use shell holders instead of the aluminum, junk. I also put a couple of cotton balls inside to protect the bullet. I use one of two items to hit against, the first being a heavy block of wood and strike against the end grain. I also have a piece of 1" steel plate about 3" x 5". Both seen to work well, but the steel annoys my wife as we share office space and that is where my loading setup is.
