Those are definately great prices from both Natchez and Midsouth excluding the unknown shipping charges. It is the same kit I started with but as stated above, you will need accessories to go with it such as calipers, etc.
Another good source for supplies besides your local gun shop who needs your support is Midway USA. They have sales all the time as I just picked up some Nosler .224 bullets at a pretty good price in a Varmit pack that cut $0.06 a piece off the local price. As much as I shoot Noslers, that is a huge difference.
