Fallout 4: How and Where to Get More Ammo

Check Your Perks

First things first, take a look at the perks under Luck. There is a perk called Scrounger which gives you the ability to find even more ammo in containers around the wasteland. The more points you put into it, the more ammo you’re gonna find on your travels. This is a sure fire way to make those safes, ammo boxes, and cash registers a lot more lucrative.

If you want to make the most out of your caps when going to trade with a vendor, look at putting some points into Charisma. The Cap Collector perk can help you to buy for cheaper, and sell for much higher, meaning you can get more bang (literally), for your buck.
