I used my scoped 1909 Argentine Mauser in the monthly silhouette match last Saturday and had some luck...39/40. I missed a turkey on my 39th shot... To add insult to injury, after the match I discovered that my scope mounts were a little loose.
Here are the match results. Note that the match director erroneously listed my rifle as an M-96 Swede. It was, in fact, my '09 Argentine.
A picture of my '09 (please note that the previous owner drilled and tapped it...)
