You can bring unlimited stuff into the Big Empty at the start, as long as you can lug it to the satellite location. So what are you bringing with? At level 40, I carry with me the following (Hardcore on, of course): Pulse Gun and a buttload of surplus SEC. you can have a selection of small energy pistols and free repair for them, so you can save repair for this baby. Normal SEC got transform into max charge then bringing along. The max charge are for the OWB pistols, and the surplus is for pulse gun. Survivalist Rifle and a buttload of 12.7mm rounds. 2000 at least if not more. At very hard level40, the respawn rate of Sink is not enough to replenish ammo for the horrendous combat with the monstrous enemies. And 12.7mm is rare. Riot Shotgun and a buttload of slugshot. Normal ammo wont cut it, so slugs are the way. Make your buckshotmagnum on the other side if you feel like it. Weapon Repair Kit: The Sink can repair at cutthroat price, so you have to repair yourself. Though you can gather material to make kits, it's very much advisable to bring it from the start. Ammo materials: At component state they are nearly weightless. So bring a lot and make some more on field benches. The Sink sell primer but no where near enough powders. If you want to carry sniping guns into MT, also bring your own store of ammo for it. At level40+, The Sink wont sell enough ammo for the rate you burn through it.
