A Rare 9.5mm cal. Peterlongo Take-Down Mauser - cased

I wonder if anyone else saw this at auction this weekend. Its the best Peterlongo I have ever seen. The 9.5 caliber is actually a .375 caliber - but not sure if its a 9.5x57, or a 9.5x60 cartridge, or ?? ... anyone with info on what this caliber might be, please chime in. And .... its on the way to join its big brother here in Wisconsin.

as always, your comments are most welcome.

Very fine rifle . And the details of the build is just great .

9.3 X 60 PETERLONGO - Cartridge Collector

Only cartridge I saw that is somewhat similar

What did the cast say on its measures ?

I wont have the rifle in hand for another 7 to 10 days so I can't measure the chamber cast, but the IAA forum discusses and shows a 9.5x60 Peterlongo cartridge. It looks like it may be a shorter version of the 11.2x72 Schuler, except in 9.5 mm caliber - which is a .375 dia. bullet. Hope it turns out to be such as I have plenty 11.2x72 Schuler brass that I can form into 9.5x60.

Hello All,

I got the rifle in hand yesterday and I couldn't be more pleased. The rifle is a 9.5mm Peterlongo caliber. A .375 dia bore. I have shown the proof stamps that I found on the barrel and hope someone can explain their meaning. I also show 5 cartridges that I loaded and a case label I made for the rifle's case, I used the chamber cast to get the cartridge dimensions. Its rebated case made from 375 H&H brass with the belt removed and the head rebated. They are loaded with a fire-forming load of 56g of IMR4064 and a 235g Speer bullet.

UPDATE:

Back from the range today. Here is the results of firing the 5 loaded cartridges. see target below. This first outing was with fire-forming loads. According to loading data for the 376 Steyr, shown in the book, African Dangerous Game Cartridges, by Pierre van der Walt, I assume the 9.5 Peterlongo cartridge will be capable of matching the performance of the 376 Steyr, which is capable of 2870fps with a 235g bullet, 2600fps with a 270g bullet, and 2500fps with a 300g bullet.

Also shown is a comparison of different cartridges and their case capacity in terms of grains of water.

375 Whelen .... 74.5g H2O
9.3x62 Mauser ..... 74.8g H2)
9.5x60 Mauser ..... 78.2g H2O
376 Steyr ..... 79.3g H2O
9.5mm Peterlongo ..... 84.0g H2O
9.3x74R ..... 84.2g H2O
375 Taylor ..... 87.9g H2O

Very good you found out of the cartridge and how to get the brass for it . Looks like a balanced cartridge they made there and one to work with further .

Hello all,

As mentioned in a prior post, I made cartridges for my newly acquired rifle in 9.5 Peterlongo caliber by modifying 375 H&H brass. It took me 20 hours to make 25 pieces of brass. For those that may be interested, and those that may need to make custom cases, the following captioned pictures tells the process of how I made them.
