Aware, but this is not the 8x 64IS, It is called the Mazon to avoid confusion. There was a thread here about someone having the reamer and loaning it to another group member.
this is the class of the 8 rem mag/8x68 or a 375 Ruger necked down.
7x64/8x64/8-06 are one case family, 9x64 is an entirely different breed.
if taking 200 grainers such as partition or Accubond as reference: The DEVA load book gives the 8x64 about 200 fps extra speed over the 8x57, the 8x68 is pretty much has another 200 fps advantage, In the 8x64 with modern...
I have two guns in 9.3 x375 Ruger or 9.3 CANADIAN for the past 10 years, it's an excellent wildcat and was born out of my frustration with getting 9.3 x 64 brass. Replicates and slightly better what the 9.3 x 64 does I get 2740 FPS with 286 grainers such as Northfork CUP, Lapua Mega, Privi, ...
Barnes gives load data to 51k PSI as per SAAMI,
Vihtavuori lists modern Data for 6.5x55 SKAN/ SE for 380 KPA which is about the 55.000 PSI that you are looking for.
Slow powders is what you want RL 26/Magnum/ MRP or N550/555/560.
you are aware that GSC in SA shut down in 2019 and in the US in 2020? the SA business part was signed over to the brothers Landmann and may still exist
incorrect, anything S is the later bore size of .323, no S= .318
rimmed versions of either are 8 mm IR or IRS, non rimmed ( much more common) 8 mm I or IS
I have 100 rounds of ADG in 300 PRC ( to make into 9.3 wildcat), I know it's been written that it's thicker walled but at the same trim length it actually is 10 gr lighter than Hornady brass. Just wondering where the material would come from to make the wall thicker
Hodgon loads with CFE223 get you 2920 fps with 48kCUP, so this could be around 55kCUP, which is not bad for a modern rifle. But it is beyond CIP/SAAMI.
I saw the rifle when it was for sale in a gunshop in Calgary, 5 or s years ago, if that was the same gun. it had beautiful wood and I was very close to replacing my CZ550 with it. It tugs on my heart that the gun will now likely go south.
Same thing here, I had a wish list for North Forks, they have just cancelled it as they did not receive any delivery for 1.5 years. Could you comment on whether you will resume supplying hunters in Canada in the new future?
I bought, when still available, a good batch of GSC 255 gr that go at 3200 fps fly nice and flat to 300 y, BC is just .24 but this is still plenty of energy for anything in North America.
I think GS-custom US went down due to business issues of Gerard's, around 2017, not sure if there are any...
Leupold VX 6 1-6 on a 416 Rigby, good field of view at 1x, about 150 rounds fired, no issues.
I suspect the lower grade Leupolds are of a similar quality
I still have some of his 3rd generation KJG in 7mm, 105 gr at 3550 fps out of a 7 RM with RL 17, most precise bullet I ever found, no hold over for varmints to 350 y. Perfect for longrange wolf in the north with the bait in the middle of the fraser river.
9.3x62, 1938 DWM Mauser, Heym Match grade barrel, 50 cm, Ralf Martini made stock of Birds Eye maple, Recknagel safety, Timney trigger, shoots 155 gr MJG as a deer and moose load.
I find the NX8 have a very small eyebox and need optimal cheekweld. I am much happier with Leupold VX6 1-6 ( 416 rigby) and Vx 6 2-12 on a 9.3x375, much better field of vision. Maybe not quite as robust.
you are dealing with a number of variables and without pressure testing ( which generally is easier to obtain in Europe) you can only guess where you are pressure wise. Your best approximator is measuring bullet speed ( Garmin Xero's are comparably cheap)
The major variables are
-brass (...
this is a military 98 action, original is standard length ( cut-out for loading strips on the left). It will have major modifications/lengthening of the action to fit a 375H&H, it was made for 8x57IS. Whether this is any good depends on the metallurgic skills of the gunsmith/welder. Also the...
Agree with all he says, the rimless variants are the wildcats based on 8x64, 375 Ruger ( as I have it) 300 WSM, with similar velocities, but all at higher pressures and not rimmed.
So this cartridge ( at 366 or 375) certainly fills a niche. I like it.
prions are " denatured" neurotropic proteins, they made it from dead sheep via heat processed feed into elk and cattle. And from Cattle to humans, especially in Switzerland and England where that feed was employed. So I would not eat anything that has tested positive for any prion disease
for...
this is understating things for the 9.3x64: for 286 gr you are getting to 2750 fps with medium burnrate powders ( Varget, H4350) and even more with powders in the 4831 range.
the 9.3x62 tapers 0.02 " from base to shoulder, the 30-06 0.03", the 280AI 0.015",
Let's say you want to keep a taper of 0.015 for sake of extraction, then the gain in powder capacity is minimal woth a 9.3x62. And you WANT reliable extraction in Africa ( or anywhere). Handloads can take you...
I think they were the Frankonia house brand in Germany. Forest Favorit. Different makers over the years. The picture you posted is likely an FN action or similar, not a sporterized military. Good quality
