Updated--The 131 acre wildfire south of Fillmore was fully contained as of Monday morning.
Three firefighters suffered minor injuries.
The cause of the fire was someone doing target practice on private property.
The brushfire was reported around 11:45 AM Sunday along South Mountain Road west of Bardsdale.
The flames spread quickly in light to medium brush.
No structures damaged or lost.
The Ventura County Sheriff's Department says no evacuations were ordered and all the major roads in that area remain open but motorists should avoid South Mountain Road in that area because of all the fire equipment moving in, out, and around.
Deputies were also searching for someone flying a drone in that are which is threatening to halt the firefighting efforts from the air.
The fire was confined to an area south of South Mountain Road, east of Balcom Canyon, north of the ridgeline and west of Bardsdale cemetery.
More than 300 personnel and equipment from throughout California were assigned to the fire and many are expected to be out there all night to work on full containment and control and to deal with any flare-ups should they occur.
But other personnel and equipment are being released including all air tankers.
Several water dropping helicopters and air tankers with fire retardant, several hand crews, bulldozers, support personnel and several engine companies with what are know as type-3 engines which are designed to work on narrow dirt roads, rugged terrain, and tight spaces responded to the fire at one point.
