Few things...
First, when you say sniper rifle, do you mean the anti-materiel rifle? Because that one uses .50 caliber bullets and I've yet to find them in the Wasteland, that I can remember. However, the actual sniper rifle (and the Gobi sniper rifle), along with the hunting rifle, use .308 bullets. And I've found those across the Mojave, and on enemies. Not always AP or HP rounds, but still.
Second, I've only ever bought a few weapons. I've found most of my weapons (and to the best of my knowledge, you can't really buy the uniques).
Third, with regard to repairs, make sure you get your repair skill up, and then try and land the Jury Rigging perk. Helps a lot. You can repair any armor with similar ranked armor (Light with light, medium with medium, etc), and any weapon with a similar weapon.
Finally, specifically with scavenging, vendors will buy anything, from bent tin cans to conductors/fission batteries/etc. I usually do a few scavenging runs, where I head to Novac, dump off all but the most essential weighted items (I'm not in hardcoe mode), for myself and my companions. Then I go around, scavenging anything with a decent weight-to-value ratio. If I come across enemies, I make sure to take their weapons and ammo, and if they're similar, I repair them up (now that I have the jury rigging, it's easier). I then head to Gun Runners, and I've found them to have 8000 caps when restocked. I then trade my crap for bullets (and occasionally, weapons). I never make a ton of caps, but it's more than enough to keep the ammo well stocked. If I wanted to, however, I could very well make 8000 caps off of one sale to Gun Runners. You just have to be willing to spend time collecting junk.
