Hey Jeff,
I believe the 175 grain Sierra was actually designed for 8mm Mauser velocities. I use them in my two 8x57s for warming up with mild loads. I use the 200 grain Partions and Accubonds for hunting. Never had a chance to test on elk yet, but they sure work well on deer sized game. I would think the Horndaddy will do fine for elk and the 175 will do deer well in the 325. I'll get a good opportunity for an elk test with the 8x57 and the 200 grainers later this week. I would love to test some of the 195s myself.
