Deadlands - How to set up Fanning the Hammer

[Maetco]

I checked the Fanning the Hammer video in the sticky, but it seems to be outdated. In the video there is no number of bullets visible. When I made the fanning the hammer as it was done in the video, the attack consumes 50 bullets and I didn't find a way to change this.

You either have to disable ammo, or write and extension, firing 6 shots RAW in SWADE is 50 bullets.
