You can sneak to the brno in the upper caves at 1st level with 3 agi if you max stealth and get decent stealth gear. With decent pickpocket, you have a huge amount of 8.6 to steal from sgs guards, a few random people in junkyard, and the embassy guards (and later SRO and praetorians and probably many others). You can go well into the lategame without ever buying ammo if you stick with the brno, but regardless its a great way to get through the early game on an lmg build.
