.375 H&H with 350 Gr Bullets
      #14732 - 14/05/04 04:41 AM

Has anyone load data and shooting results with the 350 grain bullet? What sort of velocity are you getting? Also does anyone have a 375 low pressure load for doubles?

I have shot several Buffalo with them..I loaded some RL-15 with 350 gr. woodleigh softs at about 2375 FPS and they worked just fine..I also used the 450 gr. 416s and shot 9 Buffalo with them last year..They are an excellent bullet. I used the round nose version..this year I will use the PP in the same weights, they seem to have more penitration in my limited use of them....

I'm picking up a new merkel 140-2 today and after much consideration, I went with the .375 over the .470 for many reasons: 1: Recoil 2: Cost 3: Stress on the gun. I'm happy you came back with positive feedback on the 350's. Once I pay this baby off, I'm going going on safari with it.

Ray

Were these compressed loads for the .375? Where did you find the load data? Thanks

Best be careful as I believe Ray is giving Bolt Rifle loadings and not Double Rifle loadings with the 350 grain.

You can load the 350 farther out in a Double and put in way too much powder for the lower pressure action.

Thanks Mick, but it is OK because I will be using them in a BRNO 602.

bonanza50, be careful with reccomended loads for the 375 H&H belted magnum in your DOUBLE RIFLE! The S/S double rifle is not the place to go experimenting with loads when chambered for cartridges like the 375 H&H BELTED MAGNUM! The loads Ray gave you are for bolt action rifles, it is well known he will not own a double rifle chambered for a high intensive cartridge like the 375 H&H B.M, or 416 Rigby. Both are in the 45,000 to 60,000 psi range with common hand loads, and even some factory are too hot for doubles. IMO a 375 H&H Belted Magnum should be kept in the loading not to surpass the loads for the 375 H&H flanged. Also do not use monolithic solids in the double. Your best bet is a load for the flanged 375, with the 300 gr Woodliegh softs, and solids, useing a 375 H&H flanged loads worked up till they regulate! Though your rifle was made today, it is still 17th century technology, and will not tollerate the high pressures of a bolt rifle, for long, if at all!

Not sure what you want to hunt, but the only way you are going to get low pressure loads for .375 Flanged Magnum that shoot parallel in a double, is to shoot lighter pills.

Here is a load that shot quite well for me;

Projectile: 235 gr. Speer Semi Spitzer
Case: BELL
Primer:Remington 91/2
Powder: IMR 4064 - 72 gr.
MV: 2650 fps

For "plinking" and use on light-skinned game, the Hornady (or Taipan) 220 gr. Flat Nose pills with 1-2 extra grains of powder can be driven at MV's up around 2750 fps.

Dugaboy, what kind of damage could occur shooting the 375 H&H belted magnum in DR? And, why do merkel and other makers offer it?
BTW I just shot it for the first time today, a full box, seams tight as ever.
Painted a nice 3" 8 round group centered 1.5 inches high at fifty yards off hand - perfect.

Mickey 1,
I perceived the question as referring to the 375 H&H as stated by the poster, which was correct it turns out, with a second incorporated question by said poster as to the double rifle to wit the word "also" and to wit I had no knowledge thereof... therefore if you cannot answer the question then one must dazzle them with BS on such forums!

Adam,
No it is not a compacted load, it is a full load to the base of the bullet with a small amount of tuck...I had to work that one up myself as no loading data was available, so I confleberated the condensed knowledge of all reloading manuals and came to a starting point and proceeding from there...Worked out to my satisfaction with RL-15. I will probably do some more loading work on the 350 gr. bullets at some point, but I will use this load in Africa once again this year..

I used these loads last year for Geoff McDonald of Woodleigh who furnished me with PP and RN bullets in 375 350 gr. and 416 450 gr. to test for him...

He and I communicated for a year prior to the manufacturer of these bullets upon my suggestion that we needed a heavier source of bullets for both calibers...I insisted on the RN and Geoff was sure the PP was the best route, both worked well indeed, but I believe that Geoff was correct, the PP is the better bullet of the two IMO now that I have used both..

The PP has more penitration....but the RN may, in fact, be a better herd shooting bullet as it tends to expand to great size and stop on the off side skin of Buff...I seldom hunt in herds if I can get out of it so my choice of the PP these days.

Just got of the phone with the Merkel rep at GSI and he said the gun can easily stand up to factory 375H&H loads and in fact are regulated with them. I will take your advice and load up a batch stepped down to 2350-2400 fps. No point beating myself and the rifle up just practicing, and use the full throttle load on safari. BTW I want to hunt Caped Buffalo next year.

Please don't be offended but I would get that gentlemen's name and get it in writing. Document all ammunition you shoot and keep the record with the letter.

The gun comes with a 1 year unconditional warranty. A fellow at my club has one and when his stock cracked they replaced free of charge even after one year.

Do you think U/O doubles (with what i think may be called the "blitz" action ie double top cross bolts) is stronger than the S/S?. What pressures would you go to in an U/O?

Mike,

The Blitz action is the German trigger plate action.

The action you refer to is the Kirsten action.

It ought to be strong as hell, and I have wondered the same.

Here's a Kirsten action:



This is a Merkel 323E in .375 H&H.

Best to you,

Did you get the FP Taipans to regulate in your rifle?

The guy at Merkel could say little else, but the truth is the Merkles have had problems from the start with the 375 and 416s, they shoot off the face, to much pressure for the doubles action....Listen to Mickey1...

But worse than that, a belted round in a double can slip the ejectors and jam up the gun to the point that it is very difficult to repair...and if that happens on an elephant or Buffalo it can be a bit of a problem sometimes.

Just my call and your certainly welcome to pick your own guns....

I had my 375 regulated with Kynoch 300gr (Woodleigh).

David Little at Kynoch says they produce an average of 30-32K psi. (that's half of SAAMI's 60K!) He even went as far as to test some from a specific lot number that I sent him and confirmed that they were in that range.

I posed the question at AR as to how he's doing this, and the consensus seems to be that there must be some special non-canister powder he's using.

That doesn't help you with a relaod, but it's the lowest pressure 375 ammo I've seen or heard of.

PS - the lowest pressure psi "Measured" load i've seen is from Accurate Powder.
300 gr w/ 83.0 gr of thier 3100 produces 2305 fps at 40K psi.
for 350 gr w/ 73.0 gr of their 3100 produces 2106 fps at 36K psi.

.375 H&H w/ 350 gr & .416 w/ 450 gr [Re: bonanza50]
      #23443 - 04/01/05 11:37 AM

dear bonanza 50,

i assume you are thinking of the wonderful 350 gr woodleigh weldcores?

strictly for the turnbolt .375 belted H&H, not the double, here is some info:

350 gr woodleigh weldcores
H4350 68 grains 2300 fps
H4350 72 grains 2380 fps
H4831SC 73 grains 2250 fps

i got all these loads from Mr Geoff McDonald of Woodleigh, a very fine gentleman indeed.

my pre-64 super grade .375 prefers the H4831SC for accuracy, but also handles the H4350 with aplomb, 70 grains for 2350 ft/sec.

obviously after i got the info from Mr McDonald, i started off w/ 10% lower loads etc etc.

somebody above mentioned 416 rigby loads:
Mr McDonald recommended these loads for Woodleigh's 450 gr. bullet in the 416 Rigby:
H4831SC 94 grains Federal 215 primer 2300 fps
H1000 100-105 grains Federal 215 primer 2100-2200 fps

i have not tried these out because i recently traded in my .416 on a dakota 76 in 404 jeffery.

by the way, this info from woodleigh is fairly current, Mr McDonald gave it to me last july (2004).

good luck and good hunting!
