I had no trouble with 200 watts into a 215 for MANY years against two guitarists and dynamic drummer. Yes I have 500 now with either a 412 or 212, but I never get to turn the master up much at all.

I'm sorry but you guys really don't have enough information to make recommendations at this point. Just saying "300W and a 4-10" still leaves a gagillion possibilities. I would argue that there's no comparison between a 300W SVT with an Ampeg 410HLF Pro (stupid loud) 4-10 and a Behringer 300W head with a Fender Rumble 4-10. They are worlds apart. They don't even belong in the same conversation as far as volume OR budget (never mind tone).
The guy is asking about watts and volume. He needs to understand the concept that he is asking the wrong question first. And THEN we can lend a hand to help him figure out a first rig.
As far as "under 300W is a waste of time", that's a ridiculous statement. I have run an Ampeg V4 (ONE hundred watts) with an 8-10 cab and I dare you to bring me a drummer or any two guitar players I can't keep up with using that rig. I filled a club with no PA support using that setup. I have also run an SVT 6 pro (ELEVEN hundred watts) with the wrong 4-10 cab and couldn't even hear myself on stage nearly killing the cab. Watts don't mean squat.
Watts do mean squat, but they're certainly not the be-all and end-all of loudness.
I can't believe you want to bat this out again, and again, and again.No
Double the amp power, everything else the same, gives you less than ONE dB SPL (acoustic power) increase. Double the speakers and the power and you will get about +3dB SPL (acoustic) power. It will vary a little due to various coupling, loss and propagation issues. If you have an amp with a dB meter on it and a SPL app for your smartphone you can see this for yourself very easily.
3 dB SPL is accepted as the minimal step that most people can hear. It is actually twice as loud according to the definition of the dB scale. However, in a subjective measurement, what many people would says is "twice as loud" to their ear may be closer to 10 dB - 10 times - louder.

And don't forget to wear earplugs. That ringing in the ears is not a good thing, especially in the long run. Not to get on a soapbox or anything, but it is a big deal.
My first real bass amp in high school was a Peavey TNT115. 150 watts, 1-15" speaker. It was plenty loud enough for a drummer and 2 guitars. Something like a GK MB combo would be great, You can always buy one of the powered cabinets to go with it later.
