Fallout – How many extra pellets are fired from a Two Shot Prefix Shotgun

fallout-4

I was looking at the legendary weapon effects wikia page and came to the two shot entry. It says that it "fires an additional projectile." I remembered that I recently found a two shot combat shotgun. Does its prefix mean that it fires one more pellet or twice the pellets when compared to a normal combat shotgun?

Best Answer

Well, let's put the speculations aside and test it experimentally!

If we compare two identical stock double-barrel shotgun (With a long barrel) in our inventory, we can see that the predicted damage for the shotgun with Two-Shot is already twice the damage of the standard shotgun:

Expected damage comparison

If we test it point-blank on a gentle Deathclaw, we can observe the real damage difference between the two shots, which is just over 2x:

Live Damage comparison

The slight difference can be explained by the pellets spread. I tried to reduce it to the maximum by using the Long Barrel mod and having my character placed at the exact same spot, doing a Body shot in VATS

So, in conclusion, Two-Shot will fire twice the amount of pellets from a shotgun doing correctly twice the damage.
