400 H&H and more

[russlate]

Holland and Holland will be introducing the 400 H&H cartridge - and a 465 H&H cartridge.

The 400 will be brought out on a necked up 375 case and will use the .411 bullets from Woodleigh as are already used in the 450/400. This is designed to a) provide a 20% increase in muzzle energy and b) the same energy at 100 yards that the 375 has at the muzzle.

The 465 H&H will be based on the 378 Weatherby sized case and will throw a .468 caliber 480 grain bullet ( used in the 465 NE ) from the Weatherby case reduced to H&H's standard long tapered shape. It is designed to match the 400 H&H's muzzle energy at 100 yards.

375 H&H = 4161 ft. lbs. m.e.
400 H&H = 5011 ft. lbs. m.e.
465 H&H = 6013 ft. lbs. m.e.

Now if they'd just bring back the old 300 H&H which gave you a gentle shove rather that a harsh slap to it's recoil, I'd be in hog heaven. Maybe even bring back the 350 H&H ( aka the 350 Griffin and Howe ). More to come out at the upcoming SCI.

Here's the link to the info - oops, this time it works!

Sounds interesting - but I'd really prefer an extra 100-200 fps on that .400... when dealing with things with teeth, hooves and horns, every little helps!

Moving this to the Hunting forum, where it's likely to attract more interest.

So the .400 H&H with its 0.411" bullet essentially duplicates .416 Remington ballistics, but it does so using non-standard components. Wonderful.

And the .465 H&H uses an uncommon .468 bullet with both less sectional density and less energy than the standard .458 bullet in the parent cartridge. Doubly wonderful.

As a potential customer, I fail to see what tangible advantage these cartridges offer over cartridges more readily available which give the users more flexibility in both factory and handloaded ammo.

Well, my .375H&H seems to do the job just fine.

You know when your rifle cartidges start to look like pantanella cigars you really should be shooting at hippos or something.

Unless your deer is hiding behind a 1948 Desoto.

That's some seriously scary ballistics.

Being the example of common sense and restraint that i am when it comes to heavy rifles..........I think it's pretty cool but...The 458 Lott has become king and H&H is I'm afraid a day late and a dollar short on the .465. The Lott is just too easy and it just makes sense.

the .400 has some real potential I think. But see the above as compared to a .416 Rem.

Of course I'd never own something that exotic...

Why not just lengthen a 45-70 case (45-110?) and use that instead? Common bullets and primers...

 

[H&Hhunter]

Oleg,
Ok that'd work too. But we already have that in the .458 Lott. And it's comercially available and really easy to do. And chambered in Winchester and Ruger rifles off the shelf.

The .40 H&H was developed out of concern that the .416 Remington have pressure peak problems in extreme hot climates. H&H is delibratly loading it to lower pressures and with a gentler shoulder for optimum feed reliability.

Remember the .416 Remington is based on the 8mm Rem Mag, it's loaded very hot and has a 25 degree shoulder for the North American hunter.

It's putting out the same weight bullet (400 grains) at almost the same velocity (2375 vs 2400) as the Remington. The H&H bullet is a few thousandths of an inch smaller in diameter. From sketches at the African Hunter site linked in a previous post the tapered case with LONG neck looks like it ought to have noticeably less capacity than the Remington's.

A smaller diameter bullet out of a smaller capacity case sounds like a recipe for higher pressures, not lower, assuming optimum powders are used in both.

The BIG plus for the Lott is it's ability to digest .458Win Mag in a pinch. The 500grains at 2200 don't hurt either!
