My first 7x57

[yamoon]

My Orberndorf model B was built with a 20 inch part octagon barrel. It barks pretty loud, Proofed in 1912. I like 8x57 but intend to own a 7x57 when I find one I like and can afford. Would like a 6.5x57 also.

I was suprized when I found a 7x57 before an 8 mm seeing has how more 98’s were made in 8mm than 7x57 mm.

Wow I have never even heard of a 9x71 Peterlongo. Is it a smokeless powder or black powder round. I have taken deer and boar with a 1905 Mannlicher Schoenauer in 9x56 proofed in 1921. As well as a Remington model 14A in 30 remington made in 1920. I love bringing these classic old rifles back to hunting shape and using them in the way they were designed to be used.

Nothing like being a month late....

I'm doing this from memory so any mistakes are unintentional. Johann Peterlongo was a maker in Innsbruk who developed a line of quite powerful cartridges based on a 71mm case. I think the 9 X 71 was introduced about 1919. For the 9 X 71, think 35 Whelen on steroids. However, I'm shooting a 200 gr. cast bullet at about 1900 fps. I did work up a 200 gr. jacketed load at 2550 fps. and there's room to go higher but I can't imagine why a fella would want to. I have a picture but can't find it. Some stateside dolt ground off the rear octagon part of the barrel, removed the rib, added a white line spacer and recoil pad and a Lyman receiver sight.....which required a taller front sight. The dolt did a good job as it took me a couple months to figure out what was done. I don't know if it was ever fired after that work was done because I had to make the brass from 9.3 X 74R and work up the loads. I doubt the previous owner ran down to the local Mom and Pop sporting goods store and bought ammo.

IMG_6094.jpg I just picked up a Mauser 98 B model in 8x57 but I think it takes the 318 bullet even though it was proofed in 1937. What are these raised wood sideplates called ?IMG_6090.jpg IMG_6090.jpg

Ms9x56,
Technically, it was supposed to take a .318" bullet but, as Axel informed us, shortly after the Versailles Treaty Mauser throated their 8mm barrels for .323" bullets, even in nominal .318" barrels. It was discovered during the change over from 8X57I to 8X57IS chambers so throated did not create excessive pressure. If you fire a cartridge and the fired, unresized, case accepts easily a .323" bullet into the neck, you can use these cases with .323" bullets. If the cartridge you fired was "Factory" with .323" bullets you can continue to use it. Side panels, I think.
