This depends a great deal on how you want to display your crosshair. If you're using the most obvious method of dropping an Image UI element into the center of the canvas then a good way would be to set the pivot to the center of the reticle (which you should have already done anyway) and then simply adjust the scale using a script like this:

 public Image reticle;
 public float reticleSize = 1.0f;
 public float delta = 0.01f;
 
 Update() {
   reticleSize = Mathf.max(1.0f, reticleSize-delta);
 
   if ([player has shot])
     reticleSize += [accuracy delta value, perhaps from the weapon class];
 
   reticle.GetComponent(RectTransform).sizeDelta = new Vector2(reticleSize, reticleSize);
 }

Yeah, you know in fps games where the individual parts of the crosshair just move away from each other when shooting and come back together when stopping
