if your going to bring a gun bring something that fires .44 or .357 as those are the only amo type that spawn all other amo types spawn maybe 1/10 of the time and then it's only 20 rounds. for energy weapons you will find lots of small energy cells and MF but the energy weapons you get doesn't burn through them too quickly so you can convert them to what ever you need.
I however would only bring
lots of .44, .357, and a couple hundred .308 rounds 50mfc and 50 SEC the pulse gun and paladin toaster if you have either lots of caps HH ingredients

Pulse Gun uses a lot of SECs, but it's very handy against Roboscorpions and other high-class robots you'll be facing.
You could also try working with crap you salvage from Lobotomites and Y-17 Trauma Override Harnesses. Lobotomites may carry Brush Guns, Hunting Shotguns, .44 magnums, Super Sledges, and Saturnite Power Fists while the Trauma Harnesses carry a variety of Energy Weapons that scale to your level ranging from generic Laser Pistols to Gauss Rifles and Shishkebabs.
In case the dialogue doesn't tip you off to it, you'll be much better off exploring the entire Big MT area than leaving any of that awesome loot out there longer than needed. You're always free to return and all, but why wait? SCIENCE! can be put on hold while you nab a fancy new...green latex glove? Sure, why not?
Find yourself a Proton Axe and use it exclusively against the Scorpions. The melee ones are stunned enough not to hit you, and the ranged ones can be easily countered by strafing left and right while approaching.
