6.5 Creedmoor vs 6.5 x 55 Swedish Mauser Ammo Guide ballistics

[Gert Odendaal]

The 55000 psi SAAMI specs were set for the 6.25x55 because there are a lot of old rifles in circulation. For new modern rifles pressures of 60 000 psi can be used.

Garry, please if possible send me a link to the modern rifle pressures about the 6.5 x 55 Swedish Mauser conformation?

Garry, I assume the 1917 Carl Gustav action is still the "old" rifle or will the 60000 psi be designated for this action as well?
I got this info, wikipedia is not the most factual web page at all but it give you an idea about it:
All Swedish Mausers were chambered for the 6.5×55mm cartridge, and all Swedish-made actions were proof-tested with a single 6.5×55mm proof round developing approximately 455 MPa (65,992 psi) piezo pressure (55,000 CUP).^[4][5] Swedish Mausers were manufactured by Waffenfabrik Mauser AG in Oberndorf a/N in Germany and in Sweden by Carl Gustafs Stads Gevärsfaktori and Husqvarna Vapenfabriks Aktiebolag. All Swedish Mausers, whether built in Germany or Sweden, were fabricated using a Swedish-supplied high grade tool steel alloyed with nickel, copper, and vanadium, a product then noted for its strength and corrosion resistance

Civilian rifles built on the Swedish Mauser action[edit]

CG 63 competition/target rifle

When surplus Swedish Mausers became available after World War II many m/1896 and m/1938 rifles were successfully converted by Carl Gustafs and Norma into the CG 63 Competition/Target Rifle chambered in 6.5×55mm and 7.62×51mm NATO. A number of CG 63 match rifles were acquired by the Swedish Army, with their rifles colloquially known as Gevär 6 if in 6.5×55mm and Gevär 7 if in 7.62×51mm. These competition/target rifles were used by members of the Swedish Volunteer Sharpshooting Movement Frivilliga Skytterörelsen (FSR) and are known to be very accurate for their price. The FSR strived to keep the costs of participating in their shooting events reasonable, so the FSR rulings restricted the unchecked use of very expensive highly specialized target rifles, ammunition and other gear. The CG 63 rifle was built on a Swedish Mauser receiver, to which a new heavy, non-stepped free-floating target barrel was fitted. The vertical thumb piece was removed from the bolt to improve lock time. The triggers were adjusted and smoothed to match quality and the rifles got diopter and globe sighting lines (from several Swedish manufacturers) and target stocks. The CG 63 was further developed into the CG 73 / CG 74, also called m/74, and finally the CG 80 competition/target rifle.^[18] The CG competition/target rifles complied and evolved with the technical and dimensional FSR rulings then imposed for FSR shooting events. Starting at the end of the 20th century the FSR allowed the use of competition/target rifles that are not based on the Swedish Mauser receiver.
Husqvarna also made commercial m/1894 and m/1896 versions available as sporting rifles called Model 46 and its variants (Models 46A, 46AN and 46B) in 6.5×55mm, 9.3×57mm and 9.3×62mm. After World War II they used m/96 and m/38 actions without thumb notch to create the Model 640 series (646 in 6.5×55mm, 648 in 8×57mm, 649 in 9.3×62mm). These are not to be confused with the late-production Model 640 using FN Herstal M98 actions. Stiga also made sporterized versions in popular calibers, which are very well finished and balanced.

Here is a very good PDF file about the history of the Swedish Mauser ,.

Your rifle is the original old Mauser M1896 rifle design which is identifiable from the stripper clip cut and of course markings, the higher pressures are for the modern rifles like Sako, Tikka, Husqvarna etc. in 6.5X55.

Here's Vihtavuori reloading data for the old rifles: https://www.vihtavuori.com/reloading.../?cartridge=71

AK-Gunner, how available is the K31 7.5X55 Swiss rifle and scope mounts in Finland?

[AK-Gunner]

I'm afraid I don't think that the rifle nor the scope mounts are available up here. Older Swiss rifles haven't really been 'a thing' in Finland because we don't share any common history with the Swiss armed forces.

Yes indeed, from this message https://www.gunsite.co.za/forums/sho...=1#post1323613 begins the story of my visit two years ago during which I spent two days hunting Kudu. You may find the story interesting, not just the hunting part

[Gert Odendaal]

AK-Gunner, great experience for sure. Cordite crazy is one of our permanent hunters on the 1885 Black powder hunt we conduct every year. Consider participating in the 1885 Black Powder hunt , it is a great experience and you will never experience such a hunt anywhere in the world like this type of re-enactment hunt.
