Anybody got the 3d Edition Vihtavuori Oy Manual?

If there are any N560 loads for the .375 H&H Magnum, could you please post the data (bullet type/weight, powder charge, and muzzle velocity)?

Thanks.

Russel, sorry they list nothing but the N1** powders with this cartridge [Frown]

Russell,
Some answer in the afternoon, but by my experience, the 500 series are a little slower than the 100 series, and they are quietly interchangeable. A characteristic: in more noisy than 100 series powders.

Russell, a quick e-mail to Vihta Vuori has always helped me when I have needed some help. They seem to respond promptly about powder and load questions. FWIW

Yes, I've done that before, too, but generally just get responses that are in line with their published data. Same thing with Hodgdon. Just once, I'd like to write about a "non-standard" powder to some manufacturer and get an "unofficial" response like "You know, we don't have it published for legal reasons, but we've actually had good luck with _______ grains of _________ ."

I've just accepted that I'm on my own in most cases, unless one of you guys have ventured down the same path previously.

Thanks.

Russell,
I had the same answer when I asked info on 9.3x62 to load it with 293grs Tug Bullet. I had to develop my own data.

I've not found any 375HH load data wit 500 series powder.

I can only confirm my previous mail. If you make some test you will probably find that it is possible to exceed the 100 series powder load data.

Russ, I have three pressure-tested N 540 loading data here. However, they are from the DEVA reloading handbook 4th ed., not from Vihtavuori as you stipulated, so I doubt that's what you want ;-P.

Regards,
Carcano

I am wondering about this VV powder. I am seeing an indication that these 5 series powders are yielding higher velocities at lower pressures and I am also curious about some of the slower powders in the 100 series. Has anyone had these experiences and if so with which calibers. Just like everyone else I am looking for the best of velocities as well as the best accuracy. DRBOB

DRBOB,
I'm still testing N560. I had good results with 7x64, for a bullet of 139grs I put 63grs of N560,primer Federal GoldMatch, not Magnum. Absolutely very noisy,more than normal, but fast and precise, and with normal pressures. With other calbers I did not have the same results.
Still in test.
