I have ALWAYS wanted a double and today I found one. It’s a Heym 88b made in 2014, 99% condition.

The 450/400 is not the ballistic equivalent of a 404 Jeffery as it maxes around 2150-2200 FPS.

What’s everyone’s opinion on the caliber?
 
According to Taylor the 3-inch and 3¼-inch .450/400 NE were adequate for all African game in almost all conditions when used by an experienced hunter.

400gr bullet at 2150fps sounds quite reasonable. I also like the look of Heym 88b, to my eye it’s one of the nicest looking doubles. I actually much prefer it to 89b, but looks are just that.

What’s ammo/components availability like for it?
 
Dies and components are readily available.
 
It is in the Ruger No.1. You can get 2400 with the 400grain bullets.
 
The .450/400 NE seems to be the consensus caliber for doubles that I have seen it be recommended over and over by many hunters and pros alike. Big enough caliber for any DG and small enough for lower recoil than most.

My only concern was spending that kind of $ to find that it wasn’t enough gun. From what I’ve read in here prior to posting, it seems to be just enough.

Maybe it could be pushed to 2250 according to some members posts.

Don’t forget that it’s a double. It will be regulated for a certain load. You may or may not be able
To deviate from that load and keep acceptable accuracy.
 
Using factory ballistics a 400 grain bullet at 2,050 fps generates 3,731 ft/lbs of energy.

Next step up in traditional double calibers is .450 NE 3.25 that pushes a 480 grain bullet at 2,150 for 4,925 ft/lbs.

So, it just depends on how much power you want.

Very true. How common is it to find a hand load that works as well as the load used to regulate the rifle?

The energy of the 450/400 is quite a bit lower than the 404/416 Rigby which are both near 5000 ft/lbs. It also operates at much lower pressure than those two cartridges.
I would think that the 450 NE would be closer in performance.

Red Leg and Cal Pappas should weigh in on that. Way outside my expertise.
 
I should preface my statement by saying I am not a DR expert.

I have both 450/400 NE 3” and 450 NE 3 1/4”. They both make statements when I shoot these DRs but I don’t notice any significant recoil differences. I know the terminal ballistics are different between the two but I am sure they both can be lethal as long as I do my part.

So if the Heym 88B in 450/400 fits you well and you like it then you should get it unless your main quarry is an elephant.

Regards,

My PH in Limpopo, SA carried a 450/400 double when we were hunting buffalo. I was thinking about a 470 NE when I was talking to Chris Sells at Heym during the DSC show a couple of years ago and he recommended the 450/400 as a more manageable alternative. I already have a 375 H&H double, and if I get another one it will very likely be the 450/400.

I’ll be hunting plains game only next year but for 2023/24 a buff and tuskless hunt is on the table. I cant say for sure I’ll hunt elephant but I also can’t say I wont! Sure sounds exciting!
 
The 450/400 is a very well balanced load that will take anything that walks. It has the same ballistics as the original 404 Jeffery loads (IE the one all the game departments used for animal control) The muzzle velocity was bumped up to the 2300fps we see today long after the 404 made a name for its self)

Double are regulate for a specific load and trying to hod rod to higher muzzle velocity will make you a unhappy camper. With some work and time at the range I have been able to get most every premium hunting bullet (swift, northfork, CEB) to shoot as well as the rounds the rifle was regulated with.

You would be hard pressed to find a better client DG gun. I used my 450/400 on my roan and hippo on the last safari.

Good points.

One could stretch the 404 @2300 to 200 yards if need be. To what range is the 450/400 good for? “I’ve read 100 yards and in”

Good Morning x84958
I have read your post about Jamy Traut and your hunt in Caprivi. I am planning such a hunt for 2026, Oct with Jamy.
Just a question , because I will combine Caprivi and Panorama for PG, is the daily rate the same the week long, I mean the one for Caprivi or when in Panorama it will be a PG rate ?
thank you and congrats for your story.
Best regards
Philippe from France
