Thank you so much for your kind words and support , my young American friend . It is interesting to note that l have exactly the same ammunition as you have showed me in your photograph .
175 grain soft nose cartridges made from the firm , Winchester .
On a related subject , would you happen to know how many re-loads these brass cartridge cases can last ? Four re-loads perhaps ?
There are some far more experienced than I on reloading. But if you set your dies right and the chamber on the rifle is correct you can get several re-loads. I have some 30-06 brass I’ve loaded 8 times. They could probably go some more but I’m conservative. You just have to make the primer pockets are tight and the necks don’t crack.
Of course , l will provide a photograph to show on this thread , my young American friend . I do apologise for being missing from African Hunting forums for the last few days . This is the most hectic part of the year for a tea planter .
My most emphatic congratulations for your new RIFLE and CARTRIDGE!
The 7x57 was my first, and for many years my only, big game rifle. Since 1972. It was, is as I still have and use it, a DWM Original Spòrting rifle, 1893 Mauser Action. A kind of Type C model. It came to my from my great grand father! Still in its original blueing. My second 7x57 is another Mauser action 1935.
I started to reload for the 7x57 around 1974.
To make it short, I agree with the recommendations given to you about the NORMA Oryx 156 grs bullet-cartridge brand. Their cases are one of the best for reloading. Period. Actually I think there are no better options for general big game the kind of sambar deer, wild boar and so. If you will reload and if you can find them, a Hornady Interlock or Interbond in 154 or 162 grs would be another perfect combination. And relatively not too expensive.
Reloading the 7x57 is a pleasure! Very easy to obtain excelent result with almost any medium-medium slow powders. Any of the 4350 would be, to me, one of the very good powders for 150 to 160 grs bullets.
About your rifle, well, I cannot say nothing other than CONGRATULATIONS!! I have two BRNO ZKK of the same configuration and period as yours: A 601 in 308 Win and a 600 in 9,3x62. I am searching for the last 30 years for one exactly like yours, a ZKK 600 in 7x57!! I miss for ONE DAY a beautiful ZG47 in 7mm Mauser....I am still kicking in my head....
My best wishes for you !!
Hello Milan, I just watched your video on disassembling/reassembling the CZ 550. I have spent days looking for something like this. I now have no reservations taking apart my rifle. I like to do this with all my guns so I understand them "inside and out". Thank you very much for the information. It is greatly appreciated.
