How well did the 215 gn loading for the .303 perform on sambar?

Yes, I know one can kill such large deer with a .22 Hornet, but I'm not worried about a perfect lung shot. How well do the 215 gn bullets perform if the aim is a bit off and the shoulder is hit. Will the bullet's large SD allow it to get inside reliably? Or is this just not enough mass to do the job properly?

Any suggestions as to minimum bore, SD, fps, or bullet weight?
