I have shot 9 hippopotamus with 3 calibers up until now (over the years):
.375 Holland & Holland Magnum
.404 Jeffery
.600 Nitro Express
.375 Holland & Holland Magnum is what I have mostly been using (with the exception of 1 hunt where I used a .404 Jeffery & 1 hunt where I used a .600 Nitro Express).
Bullets which I have used for hunting hippopotamus (till now), were:
-RWS 300Gr round nosed steel jacketed FMJ solid factory loads
- Remington 300Gr round nosed steel jacketed FMJ factory loads (which employed Hornady bullets)
-Norma 300Gr monolithic solid factory loads
-Cutting Edge Bullets 300Gr monolithic Safari Solid (hand load)
-Barnes 300Gr TSX factory loads
- RWS 400Gr round nosed steel jacketed FMJ solid factory loads
- Labor Fur Ballistik 900Gr flat nosed tombac jacketed FMJ factory loads
I will answer the “Solids vs Expanding Bullets For Hippopotamus“ question for you:
For hippopotamus shot in the water, an expanding bullet is better. You only get the brain shot. The skin over the top of the head is relatively thin & so is the skull. An expanding bullet works best because not a lot of penetration is required and shock is far more important.
For hippopotamus shot on land, you’re essentially looking at both a brain shot or a body shot. The hippopotamus body skin is very thick (more than 2“) and a good deal of penetration is required in order to reach the internal vital organs. So solid bullets here really come on their own.
Back when I first started going on hunting safaris in Africa in 1974, the universal rule was to always use nothing but the most strongly constructed solids for hunting hippopotamus. And indeed, I have successfully shot most of my hippopotamuses over the years with solid bullets. The only cartridges which ever gave me a difficult time, were the RWS 400Gr round nosed steel jacketed FMJ solids for the .404 Jeffery. They used extremely thin jackets, which were also quite brittle. Penetration, thus was severely impacted.
Last year, I shot an extremely large bull hippopotamus on land with a 300Gr Barnes TSX all copper monolithic hollow point. The results were most startlingly satisfactory and It was the first time in my life that I had ever used an expanding bullet on this type of game. I think that for future hunts, a magazine full of Barnes TSX cartridges is the right answer. For hunting hippopotamus on land, they are the only expanding bullets which I can safely recommend.
Even though I have never shot a hippopotamus with a Trophy Bonded Bear Claw bullet, I have used this bullet successfully against several Cape buffalo since 1993. It is (as a matter of fact) my favorite Cape buffalo bullet. I would readily endorse their use for hunting hippopotamus in the water. Same goes for the Swift A Frame bullet. But for hunting hippopotamus on land, I would strongly recommend solids or at the very least... the Barnes TSX.
