The Bullpup HAS less wobble in the scope. First thing that jumped to my eyes (after I bought it against my initial intention). The Bullpup is easier to handle with skill level 2 or 3 than for example my Anschütz 9.3 which I have at skill level 8.
I think they gave the rifles different vlaues on sway and movement depending on the rifles weight, to balance gameplay. However, maybe they balanced it 180° reversE: the heavier rifle should have more stability, but shorter time periods before the rifle holders becomes tired and the rifle begins to move stronger.
Lay down when you shoot and LOS allows it.
Get close.

Understand that many things on weapons in the game are tuned the way they are to fulfill gamebalancing desires, not necessarily realism desires that would hold their ground when comparing to the real world stuff. This will become very evident for you if you ever wil start to try out several bows where it is about noise level and damage level. It would be pointless to have a bow that is both the most silent and most powerful in the game. So both values are somewhat antagonistic in the game. Do not compare reality to game virtuality, it only worries your player's mind and makes only sometimes any sense. Take the details of any item and weapon in the game as what it is in the game, forget what the original model is like in reality.
Rifles with good stability levels are the 7mm, the Blaser 6.5x55, maybe one would also count the Anschütz 8x57 here (or maybe I just got used to it). The Anschütz 9.3 is one of the more unstabile rifles, and so is more difficult to use (plus it has more bulletdrop over pong range, you need to compensate for that by aiming slightly higher). The 9.3 in the game is a killer gun if handled well. But it is not the most easiest to use.
I find the increase in stability you are said to gain when raising your skill level with a given rifle, overestimated. You will see a difference when comparing level 1 and level 3. But comparing 3 and 5 already makes less obvious a difference, and beyond 6 or 7 I simply do not care for skill level raising anymore.
Much of the immersion - comes from imagination, which must not be something bad.
Clothing a good example. There is a reason why experienced players often do not care for functional clothing, but just wear what they think looks sexy (if they care at all).
