416 vs 458 Indecision

[BJH65]

This is probably the key issue for me. I had always assumed that a 458/500 would out penetrate a 416/400, but recent research has lead me to question that. Pierre van der Walt talks about this and how the penetration of the 416/400 beats all the others. I have come across this about the 416s penetration elsewhere.

Then when I saw the reaction of the buffalo to my 400 SAF I really began questioning my assumptions that the Lott would be the better elephant rifle.

My PH wants me to use the 416, probably because he and his other guides watched me place every first shot where they told me with it. But like many others here I can do the same thing with any rifle I bring--or I won't bring it.

However, a PH will almost always recommend a smaller rifle for the client. His backup rifle is an M-70 in 458 Lott, and his 500 grainer at 2250 has less
sharp recoil than my 400 grainer at 2430. We will see how I like 500 grainers at 2300.....

To use a cliche, we all know that at the "end of the day" it doesn't matter what I choose as all the options work. It's just fun to think and talk about them. If we didn't, we wouldn't have much of a forum...

I see this as no dilemma at all, you simply require two rifles, one in 458 Lott and one in 416 Rem Mag, although personally I would favor the 416 Rigby for nostalgia. In fact, as I type this, looks like I’ll be adding a 458 Lott to the stable which would accompany my 416 Rigby as my two large bore African rifles.

You’ve given this more thought than I’ve ever given a rifle or cartridge, but I have to ask why you want a Rokstok? I looked it up and your description is for shooting prone? I’ve hunted a lot in Africa and aside from eastern cape and croc the opportunity for a prone shot is very limited. Curious why you want that stock especially for that class cartridge.

.450 Rigby. Problem solved. Well, I actually just complicated the equation.

I love them both but they are different. I just went to the range a week ago with @CoElkHunter and his CZ 416 Rigby and my 458WinMag. Now his CZ is heavier than my Winchester by 2lbs but 458 definitely smacks you harder with a 500gr vs the Rigbys 400gr round. The Winchester has a shorter barrel too
We Doppler’d both rifles and the 458 threw a 500gr at 2170fps for 5200ftlbs the Rigby a 400gr at 2400fps for 5100ftlbs so they have equal energy but the 458 has more weight, a larger meplat, and higher sectional density. Theoretically that gives the 458 both a higher TKO and more penetration…

“You’re talking about the choice between two rather different, yet similar in some respects, calibers and rifles designed for different uses.
Now there’s no question the 416 Rigby is a bit more versatile, and will work rather well, but it’s NOT designed as a STOPPING RIFLE.
The 458 Win was designed to duplicate the ballistics and hitting power of a British dangerous game rifles in the 450-470 caliber range, these mostly throw a 480 grain-to-520 grain bullet at between 2100fps and 2400fps, and by design mostly use or at least are intended to use solids that penetrate an elephants skull at any angle or bust both shoulders on a cape buffalo, the 458 Win is designed as a STOPPING rifle for use in stopping a charge at under 60 yards.
The 416 Rigby, like the 375 H&H, is fully capable of killing anything in Africa but it’s not designed specifically as a stopping rifle.
There’s a difference between being able to kill with a single shot (which the 375 H&H and 416 Rigby do well) and stopping a charge of a truly pissed off dangerous animal at pistol shot ranges for which the added caliber (diameter & impact area) and bullet weight of the 458 calibers 500-510 grain slug have over time proven to have a sight advantage.”
AFRICAN RIFLES AND CARTRIDGES by JOHN TAYLOR

Both are awesome! Love them both so there is no wrong way to go. But the 458 is going to smack game harder. If you did go with the 458 I’d personally choose the 458Win over the 458 Lott unless I were a PH, that’s just me though…

 

[AimSmall]

Consecutive serial numbers are cool.

 

[Ruraldoc]

Of course John Taylor was something of perverse individual and much of what he said needs to be taken with a healthy dose of skepticism.

Harry Selby on the other hand was a straight shooter.

And he used a 416 for years as his only dangerous game rifle. He only switched to a 458 at the end of his career when Rigby ammo became rare and expensive.

But he never complained about the effectiveness of his 416.

When 416 Rigby ammo became available again, Selby’s younger associate Joe Coogan bought and carried a 416 as his primary dangerous game rifle.

As I said I love them both but when it comes to knockdown power and penetration the 458 has math on its side…
York, of the very popular Dalton and York, uses a 458 WinMag as his Backup/Stopping rifle in an age where most DG ammunition is available, even if in short supply. My PH told me to bring my 458WinMag not my 375 H&H or my brothers 416 Rem for my upcoming Elephant and Buff hunt. He said that without hesitation?
I’m no expert that’s for sure but I’ve seen, read, and been told the 458 and up are just in a different class?
I know I’ll be carrying a 458WinMag but would feel good with a 416 too!

I don't know why those two customers want a wooden Rokstok for a 375 and a 9.3x62. All I know is I have to make sure the stock can handle the recoil, and to do that I will start proving the concept by having the B&C CZ stock duplicated, slimed down, and laminated with carbon fiber. It's a win win for me.

 

[Flipper Dude]

Dalton uses a 458 WM as well. A push feed Mdl 70. ( Oh, the horror!)

I misread. I thought it was for your rifle.

I would agree that the 458 Lott probably hits harder, but my research indicates that it doesn't penetrate as well as the 416.

Again, this is new information to me. I had always assumed that a 458/500 at 2300 fps was about optimum penetration. It wasn't until I read Pierre van der Walt and chatted with my PH that I came across the idea that the 416/400 was the penetration king.

I don't know how they calculate penetration index, but intuitively it makes sense. The smaller diameter bullet has less resistance to overcome when passing through flesh. The 416/400 at 2400 fps seems to be a sweet spot where all the factors work in favor of penetration.

While the 458/500 does have a higher SD than a 416/400, the 458/500s SD doesn't seem to overcome its larger frontal area. Now we know that a 458/500, and even the 458/450, has enough penetration to reach an elephant's brain. In fact so does the 470 NE, which is even lower on the penetration index. So the ultimate in theoretical penetration may be a moot point.

My PHs logic is simple. The most demanding shot in terms of bullet performance in an elephant is a frontal brain shot, which is a very likely shot, and for that having the best penetrating bullet makes sense. Add to that he's already seen me shoot the 416 very well on a buffalo, and it makes sense why he would push me that way.

Anyway, that is why I ordered two barrels instead of just one. I REALLY want someone to provide definitive modern data that the 458 Lott is superior for elephant. If anyone has such data it would be Michael458, but I have pestered him so much on this topic already via PM that I don't want to call him here.

I will build the CZ as a long throated Lott and see what I get. Maybe I'll do my own penetration tests. Better yet, I'll bring my 416, the Lott, and my 470 and make the two PHs carry whichever one I don't have in my hands at the moment.......
