Holy crap, just wrapped up my first hardcore run. For whatever reason, I was compelled to try Hardcore for the first time while aiming for the "Hardly Armed But Dangerous" weekly challenge, and managed to pull it off! The RPD was by far the hardest part; battling Birkin 1 and dealing with so many zombies without the shotgun was a huge challenge. I thought for sure I wasn't going to be able to handle the return trip where you pass by the east side after activating the power generator with so few supplies. But everything after that went remarkably smooth. Got a ton of mileage out of the magnum and flamethrower on Birkins 2+. I think by the time I go for the S+ run for infinite RL/Minigun, I'll be more than ready.
