Reload while sprinting should be a perk.
Far too often some one with a double barrel wants to get right close to take shots, misses then sprints off. And if youre one of the people using melee as your secondary guess what, you cant catch up to them. Theyll reload while sprinting turn around and shot gun you to the head. Either make reloading while sprinting a perk, or create a perk that allows you to charge with a melee faster and consumes all ur stamina. (kind of like the bayonette charge in battlefield 1)
No one sprints full speed in real life while handling bullets individually,
"No one sprints full speed in real life while handling bullets individually," well in real life people also dont hunt giant spider humans that drop black rocks that let you see people through walls either.
Maybe like a half sprint or something, I'd like that.
