Thread: School me on the 7x57 mauser

Some years back a guy on the accurate reloading forum gave me a big sack full of loose 7x57 cartridges. He said the were Kynoch. I guessed they were, but wouldn’t swear to it. They are stamped with K58 and 7mm on the head. A couple of years ago when we were practicing shooting from the sticks before an African hunt, we shot a bunch of them in a Mauser 7x57 sporter of mine.

They shot very well, no misfires in spite of their age. They were berdan primed..so not reloadable by me. I assumed they were corrosive and cleaned my rifle accordingly. I still have a bunch of them in that bag. They were very accurate in my rifle.
