What stops the bolt from being pushed back into the carrier when reloading? It seams like the force from striping a round from the magazine would push the bolt back into the carrier. Does it somehow lock forward until it goes home?

There are guide rails inside the receiver that keep the bolt in the unlocked (forward) position while it is stripping a round from the magazine. Once the bolt is clear of the rails and closer to the chamber does it actually rotate to lock the round into the chamber. The rails can be seen upon field stripping the rifle, the one on the left side (with muzzle pointed away from you) also has an extra function as the ejector.

This is the best way I can think of to explain how the Kalashnikov Action works. After a round is fired, or the charging handle is pulled, the Recoil Spring pushes the Bolt and Carrier forwards, the Bolt is held in the forward position by the tension of the Recoil Spring. The Extractor on the Bolt Head strips a round from the Mag while the Recoil Spring drives the round into the Chamber, and the Bolt and Carrier into their locked positions. After you fire the weapon, the Recoil Spring is compressed and the Bolt Carrier is propelled backwards by the pressure of the expended round on the Gas Piston viva the Gas Port. As the Bolt Carrier is propelled backwards the force causes the Bolt to rotate as it rides inside the groove on the underside of the Carrier. Then the Bolt hits the end of the groove which causes the Extractor to fling out the empty casing and finally the Bolt Carrier strikes the Rear Trunnion. That ends the cycle, and the tension of the Recoil Spring pushes the Bolt forward once again. For the next cycle to begin
Hope that helps.

This video has a pretty good animation of the whole firing and chambering process.
