Hi, I've had Fallout 3 since a week after release. I've not finished the game yet mainly because of other games coming out. I'm upto retreaving the G.E.C.K, I don't know if I'm far into the game or not im guesing I'm most probably not deep into the game yet but one problem I've been having since I got the game is the lack of ammo! I find myself in fire fights constintly running out of ammo and having to go through my inventory searching for a gun that has some left. Is this just part of the game or do I just plain suck at the game? I'm guesing I just suck!

If you're zooming through the main quest, a lack of ammo is bound to happen. But if you take it slow and do other stuff, you could end up like me with 2000 + rounds of ammunition for every gun and thousands of bottle caps.

Hmmm I am flying through a little I supose, when I forst got the game I was exploring the world but for some reason stopped. would you say I'm far into the game?

 I can't remember exactly but i would say you're about 2/3 of the way through the main story.  Definitely do more side stuff and you'll end up with alot more ammo/supplies.  also, you've probably heard this a million times but the real value to this game is in the vast number of side missions.

like people have been saying, side missions and I usually also take the Scavenger perk (I think). It's the one that lets you find more ammo in containers. I'd also collect extra weapons/armor so you can sell it. Then go to moira/Flak and Shrapnel and buy all their ammo. 
 
Alternatively, put skill points into melee weapons, get the shishkebab and go nuts beating down anyone in your way.

C'mon man, you're a wanderer in the wasteland. You gotta scavenge every place you can find for food, ammo, and all your medical needs. That's what the game is all about. Embrace your inner hobo and ammo will abundantly fall from the heavens.

I opened every single last box, crate, safe and cash register in that game. So no, I didn't really have that problem.
Could always go with the melee weapons. They are surprisingly effective!

greatGuero is right.  This game is all about scavenging for... stuff.  Any and all places that have stuff to take are the places you want to be.  Everything is up for grabs in the Wastes so dont think you cant shoot a merchant in the face and take all of his ammo...

I ended up with about 18k of the Gatling Laser ammo when I got to the Citadel, and gave it all to Cross + a Gatling Laser (later Vengeance). Though that was due to abusing a glitch.
 
But, as other's have said, embrace your inner hobo, look through everything that's search-able, sell the ammo you don't use to buy more of what you do use. Even without the glitch you can easily end up with loads and loads of ammo.

I really wouldn't waste a perk on ammo, caps, or experience. You can find tons of each just by playing the game. I generally sell the grenades (cause I don't use them, and you don't want a follower using them) and spend those caps on ammo. To repeat what others have said, scrounging up thing is what Fallout is all about. If you're not exploring for the skillbooks, bobbleheads, and unique items, you're missing the heart and soul of the game.

Assuming you have dat cash:
buy out Flak. wait. Rinse and Repeat.

This game is now on my "bought it twice" list since I recently picked up the PC GOTY edition because I just couldn't get too far in the 360 version without it losing my attention.  Anyway, I'm only a bit into the game, but I've seen that taking things slow, repairing and then selling everything you can will get you the caps needed to keep your ammo supply adequately filled. 

Also, the Pitt DLC has a place that lets you turn the ammo that you don't use, into a type that you do use.
 
I did this to make every bullet in .45 rounds, so I could use the Lincoln Repeater the whole game.

wow really i always had the problem of too much ammo.

have you been taking ammo out of other guns? you can do that I do believe...

Loot everything you see.  Or just lose abit of karma for stealing peoples stuff.
 
I cheated myself abit, Just took load of small arms ammo and scrap metal to The Pitt and Pressed 2k's worth of .44 rounds for the Lincoln Repeater.

This. I had the same problem my first playthrough. But on my second I took it really slow and I am doing quite well. "

I explored every location I could find and came up with more ammo than I really needed. I also found that if I depended too much on just one gun I would start to run low, even with scavenging. For those situations you can either use caps to buy from merchants or keep a  few guns on you that use different ammo types and rotate as needed. I go with the Lincoln's repeater, a Chinese assault rifle, and third that I choose as I go, something like a plasma rifle.
 
Or you can just forgo guns and melee fools in the face.
