Wouldn’t the narrower, longer bullet have more surface area in contact with the bore?

aargh..10grade geometry AGAIN

No, I'm not doing it for you!

look up how to calculate the surface area of a cylinder.

you'll need to know the length and the diameter but after that its just math..

good luck!
All else being equal (and it almost never is) bigger bullets tend to work better.
