If you have the right taps use a metal one but I prefer to use the rubber ones because they are so much easier to install and seal. It also depends on what you want to put the valve in.
Shrader valves are capable of holding reasonably high pressures so you shouldn't have any problems. But you might want to have a look at some presta valves which are used on road bike tires because they are designed to hold higher pressures, they are similair to shrader valves.

Airbeds... so many different uses

Schrader valves should go up to 900 psi with no problems. The rubber ones still have a metal insert inside so it's not really an issue.

could the rubber break or anything? or dose the pressure hold it from the inside

The pressure keeps it shut.

All the schraders I've ever used came from bicycle or car inner tubes, I strip away the rubber then epoxy them in place. I've used many at pressures in excess of 400 psi and never had a single failure.

I only have minor experience in the 300 PSI range, (mainly because of what it cost in bike pump maintenance and replacement, what with the high-temp grease I used that one time and the hose I had to replace the other), but my best filling setup is a simple quick-disconnect setup. I have a male quick-disconnect going on a check valve into the gun, and I have an accessory I made a while back that proved itself very handy... a female quick-disconnect with a brass schrader valve threaded into it.
Threaded schrader valves cost about 10-20 cents more than rubber ones, and are just so much easier to install. Either you use them in a metal gun, and attach them to a 1/8" female fitting (duh), or you drill a 3/8" hole through a double layer on the cannon, pop the valve into the drill chuck, and then tap the threads using the schrader's threads as a tap.
