I stopped doing this when I wouldn't get the extra ammo after "aborting" the reload.Originally posted by CryptoKnight:
I now automatically switch weapons right after grabbing ammo. This aborts the reload. Sometimes I switch twice to get me back to the weapon I was carrying.
Grab ammo > Reload starts > switch weapons to stop reload > switch back to primary > no ammo.
Now I just switch to my knife beforehand then reload when it's safe.
