I have a full stock carbine in 6.5X57, a half stock rifle in 7X64 and another half stock rifle in 8X57JS. All have integral scope blocks.

I had a full stock carbine in 8X57JS, but since it lacked integral blocks, I parted with it. The receiver ring was beautifully knurled, and I couldn't bear to desecrate it with drilling and tapping for a mount. In retrospect, I might have used a G&H side mount.

Well, I know where it is, and chances are I could get it back, if I really wanted to, but I think I would have to rechamber it to 8X64S to improve on the performance.
