Dear Vidyashree,
According to previous year's cut off, there are 10 medical College who's state quota cut off for sc category was less than 300 but keep in mind that each year the cut off fluctuates due to various reason, if the previous year's trend continues then you may get a government medical seat under state quota via SC category in Karnataka.
You can check the link below to see what all colleges you may get If you are interested.
