Ive been doing a realism character and id like to know how many bottlecaps i should be able to carry at one time, realistically.

Depends. If you mod with the PC, you could get a backpack and be able to carry them in there. Really all depends on your gear and such. If you are just wearing leather armor then you probably wouldn't be able to carry alot.

in real life, you won't probably won't carry more than 200

pick a bottlecaps. feel the weight. then multiply it to 100 times.

i also hate carrying a bunch of stuff. i only carry about 50 caps myself and usually two weapons.
