That's good advice Vapo!

RCBS sells a starter kit that comes with a Rock Chuker press and has almost everything you need with the exception of calipers, powder trickler, and flash-hole debur tool. There's probably a few other things too but I can't remember off hand.

You would still need to purchase dies and shell holders for your various calibers.

Look at Cheaper than Dirt. They have a really good price on this package.

Adhere to Vapo's advice and have someone show you the ropes before you begin. Loading rifle rounds is delicate with the extreme pressures involved. It might save your life, or at least some fingers to have someone show you the do's and don'ts.
