Hallo out there
I am meanwhile the owner of this rifle, since Sept 2004, and I've shot a couple of wild boars with it-simply a great rifle, highly accurate and effective. You feel it when firing but not to compare to a 9,3x64 or even a 8x68, slightly over the 9,3x62. Yet because of the stock it flicks into sight line and you can react very fast with it. I came across 400 rounds of RWS full metal jacket some time ago, which can easily be changed for soft tips or whatever, esp. the very popular Woodleigh types. So there is enough stuff for quite a while. Triebel company in Germany provides you with excellent die sets.
As I went down in hunting somehow, I once in a while think about selling all or most of my weapons, including the mauser 10,75 - if an offer comes across that suits. More excellent information referring to this caliber to be found in hatari times from Harald Wolf in Belgium.
