Steve - I'm remembering my buddy Keith has used the 185 Remington on moose, elk, etc in his 8x68S - driving them quite hard - something over 3,000fps. At longer ranges they worked just fine and were very accurate. I almost bought a model 70 in .325 Short Mag from him and he suggested m,e using that bullet for deer through elk.
At the speeds you will get from the standard 8x57, I suspect it might be a do-all bullet. One must try them, of course.
He also liked the 196gr. Dual core Norma - the yellow plastic tipped bullet. It was a "HAMMER" on moose from his 8x68S.
