That is an understatement !!!

We had to reload at night to shoot the next day. I know I took I think 40 or 60 rounds on the place of 375H&H.

My thought are Bolt action 375H&H. That is what I found to be the best culling caliber. Larger, too much recoil, smaller doesn't have the shock value of slightly off target. That means you can easily buy ammo here in Aus quite cheaply.

BTW, the gun gets damn hot during culls.
