Ok so im at level 9 at the moment and currently have awful weapons. The best weapon i have is probably the energy rifle from the police station quest, but i've yet to find any replacement ammo.
So at the moment im stuck with a bolt action pistol from a boss i found, and a horribly outdated sniper which scratches most enemies i face. Anyone else think its pretty hard to find good weapons? Its either that or im just unlucky 

One thing that I noticed is that Fo4 gives you a decent amount of ammo - collectively. If you try to just invest in one gun, you're gonna have a bad time. I have a close range, mid range, and long range weapon of choice hot keyed that all use different ammo types.
