My Drilling is the "jrs" version of the 8x57, and it shoots "very good". It does seem to prefer heavier bullets, and "yes" i did try numerous lighter ones includeing 150 Sierra's.
For hunting i only use 200 grain Nosler partitions, and i've found them very effective on moose, deer, bear, ect....
I shot the nice buck in the picture last fall as it stood about 100 yards away, with the above Nosler load. The deer just love to come out into my food plots!!
