Could have easily just picked them up & moved them or shoved them out of the way. Shit the way it’s shown in age of ultron, thors hammer is mid throw but it looks like it’s stationary from quicksilvers pov, so even tho it’s moving SUPER fast, he can easily grab onto it. By that logic he could just run up & push the bullets off course or just snatch them out of the air. If time is basically slowed or stopped bc he’s moving so fast, he could just knock the bullets out of the air
To be fair to the hulk he gets destroyed by thanos in the comics as well so the mcu didn't do him dirty they just made the truth available in a format people actually use.
