Level 54...
1) Endless 10mil silenced with reflex. not so good damage, but the insane amount of shots I can take in VATS and ability to not reload make up for it.
2) Wazer Wifle, endless laser rifle modded to a shotgun. Yeah, it's awesome.
3) Broadsider with three shot before loading. So impractical, but with VATS, it's perfect.
4) Long range syringe rifle with long tactical scope. Rather useful with the bezerk syringe, shoot the bandit in the power armour, watch him kill a couple guys, rinse repeat until it's just him. then;
5) .50 Cal rifle with long tactical scope with extra VATS hit percentage, aim for fusion core, causes the core to blow up, the bandit to get out, which I kill the last bandit, hop in the power suit and run away.
6) For the death claws, a modified gatling laser rifle, which I lifted from the brotherhood of steel.
7) Railway rifle for the sheer joy of spiking heads, arms, or legs to the wall.
I'm currently sitting at 7 brotherhood complete power armours because I kept stealing them from the people, and 4 or 5 other shells that i have found or stolen from bandits and military checkpoints or bases.
