I've had at least one 8x57 around my entire life, 'cause my pappy sent one home (minty VZ24) after VE Day. Still have that one and a few more, all M98 variants.

Never noticed any difference between thumping a half dozen or so whitetails apiece, with a 150gr 30-06 load, or a 150gr 8x57 load? If there was any difference, the deer missed it as well.

If three or more people think you're a dimwit, chances are at least one of them is right.
