Sorry, I haven't had the need to try the 185 bullet as it wasn't available when I worked up my load. IIRC, that is a 8mm MAG designed bullet. If so, it will be fine for targets but not so grand for hunting. As velocity may be too low for reliable expansion at all but PB impacts.

According to Remington Customer Service it will work. Here is the email that the sent me.

I am wanting to reload hunting ammunition for my 8x57 Mauser. At what
velocities is the .323 185g Core-Lokt designed to expand?

Dear Aaron,
Thank you for visiting Remington Country! We certainly appreciate you taking the
time to write in with your question.
Aaron anywhere between 1600 and 2400 ft per second will be the velocities that
it will give reliable controled expansion.
Thanks,
