Hello Dewald,
GREAT RIFLES for two of my favorite cartridges you have!!!! If I would be able to choose, your FN 7x57 and your Original Sporting Oberndorf Model A Mauser 9,3x62 would be my choice, indeed!!!
Congratulations
By the way, and after have other top binoculares, all 10x42, like my formers Leica BA and Zeiss Victory HT, and after selling a Swarovski Habicht WGA 10x40, because seems redundant...I ended buying, again, a new Habicht (made in 2019) and selling the Victory HT...To me, one of the best all around hunting binoculares. Made like a tank and with optics second to none! Seems you agree...
