In our beautiful little world there are guns like pistols and rifles and for simplicity sake let's say they are of the Old West variety. In this world there also exist many beasts different and stronger than ours. The people living there are also much stronger than us, let's say 2 to 3 times stronger than the average human.
Is it realistic for an animal to not be able to be hurt by guns but be vulnerable to weapons like swords and spears and maces supposing that the users are that much stronger than humans like us?
Supposing there is defensive magic in this world and users can apply a forcefield around them that essentially acts as a barrier against physical attacks but with a certain limit. Disregarding any other type or use of magic. Is it possible that swords would have a better chance to breach said barrier than a bullet? (To help, imagine that the barriers act like plate armor just without hindering the movement of the user and is essentially weightless.)
The main difference between the two questions is that in the second, any attack that gets through is enough to remove the combatant from the fight. While in the first, animals can take much more damage before succumbing to their wounds, requiring either precision attacks in vulnerable spots, (either pre-existing due to their anatomy or created by an attack, if said attack cannot be repeated many times, e.g. limited ammo) or by repeatedly creating new wounds, supposing breaching their skin is relatively "easy" with your weapon of choice.
