You definitively can hunt in parts of the yellow area. Recreational shooting would be a no go.You won't be shooting/hunting in that yellow-shaded area. Get a forest map. Cleveland National Forest west of the 15 freeway is good to go for hunting. Need to find a point of access though. Also, the mountains around Lake Hemet (San Bernardino National Forest, I believe). Find the boundaries of the deer zones.
Hence why I use a shotgun and try and to find cost effective ammo that works.Section 4. It shall be unlawful in either the Western Zone or the Eastern Zone for any person to shoot or discharge within one mile of any incorporated city any firearm, other than a shotgun used in lawfully hunting game pursuant to a valid hunting license.
