Factually, there is enormous overlap between .375 and .416.
Sure, as everyone said already, the .375 shoots flatter, and the .416 hits harder, but there is not much that one can do, that the other one can't do, including up close, or out there...
Turning the .375 into a PG rifle with 250 gr or 235 gr slugs?
Sure, it works, but if there are going to be two calibers/rifles in my gun case, and the DG one is a .416 (or larger), then the PG one will not be a .375 but a .300.
We buy them because we like them, not because we need them...
Although I have a well established (and deserved) reputation for dry analytical thinking, I am a complete sucker for the "nostalgia safari" (
Red Leg), or 'nostalgia anything having to do with Africa'. This is why I own both a .375 H&H and .416 Rigby, but in truth since I evolved to only want to hunt DG with my .470 double (ah! the romance... and the intensity of the up-close & personal hunt of DG), neither the .375 nor the .416 have seen Africa yet...
The 1 rifle battery...
I love both my .375 H&H and .416 Rigby, and they each carry their own load of romance and nostalgia, but to me they are both a 1 rifle battery. Sentimental leanings would likely guide my choice between them, and it could be a different choice at different times
This is also why I have resisted, although I have lusted, buying a .404 (
Newboomer) because now instead of splitting hairs in halves, I would have to do it in thirds
The agony of selecting a battery...
Of course either .375, .404 or .416 could be the middle caliber between a .300 and a .470 or .500 in a 3 rifles battery, but because few of us indeed can afford a full bag, 3 months, Tanzania Safari that would justify bringing 3 rifles, practically has to intervene somewhere in the hauling of gun cases through international airports...
I am on the 2 calibers band-wagon, which may or may not mean two different rifles (can anyone spell R8? - or two barreled "mauser" actions with one stock in the same Pelican 1700 case Blaser uses
) and after two successful safaris with one time a .340 and the other time a .257, I have settled on the .300 as my PG default rifle. Depending on what is on the package, the 130 gr TTSX is a death ray and a lightning bolt on anything up to 600 lbs, and the 165 gr TTSX is Thor's own hammer on anything heavier. With 95%+ weight retention slugs, I do not use the 180 gr anymore. For DG, it is simple: .470 double. I want to hunt DG up close and personal.
This September will be PG and Buff. It will be .300 and .470.
If I did not own a .470, I would likely be agonizing over taking either .375 H&H, .416 Rigby, or .458 Lott, but I do not really see a scenario where I would take two of them together. There was a pre-double time when I swore by the combo .340 / .458, but in my mind a combo .340 / .375 make little sense, nor do .416 / .458, nor .375 / .416, unless redundancy is the intent. Of course .375 / .416 for TWO hunters (
BeeMaa) is a completely different situation altogether. In fact, each has a 1 rifle battery as discussed above...
They are a few salients points in addition to the above. If a Livingstone or Derby Eland was on the package, then the .375 with Leica 2.5-10x42 would replace the .300 also with Leica 2.5-10x42 as the PG rifle. If a dedicated lion hunt is to happen, then the .416 with Leica 1-4x24 will likely be the one.
In the end...
To each their own. As I kept telling clients on the DSC and SCI shows over these past few weeks: "
This your time, this is your money, this is your safari. Truly, do as you please, there are in the end very few rifle(s) choices that genuinely do not work."
