I have used the 87grn V-Max out to 1000 yards. It performed well when the conditions were right. It really depends on the conditions in your area. In my area the wind is not bad and most of the time very calm. So, a high BC bullet is not as important to me. I want a bullet I can shoot fast and one that explodes varmints into red mist.
However, when the wind is blowing hard, I too will swith to the higher BC bullet or rifle that is set up to shoot the high BC bullets. But to answer your question, Yes, the 87grn V-Max will perform out to around 1000 yards as long as it is pushed fast enough and the wind is calm. Your 6mm Remington will push the 87grn V-Max fast enough, so all you need to worry about is how fast the wind is going to be blowing.
