I shot an Elk at 500 yds off the sticks and a mule deer at 475. Neither time is that the shot I was hoping for, I'm much more a 100-150 yd. kind of guy by choice, but that's all that presented itself so I made it work. My PH in Africa actually gave me a tip that really helped....get a solid rest on the sticks, not wobbly or uneven and pull down firmly on the fore end as you aim and line up the shot. As you start to pull down, take a deep breath then let it out slowly until you have about 1/2-2/3 of your air remaining in your lungs. That little pressure seems to really steady things up for about 10 seconds, then you have to start over. Obviously the sticks have to be pretty solid to handle the downward pressure and weight of the rifle.
